New Technologies make the
Hawker Horizon Unique

R
aytheon Aircraft
is readying the Hawker
Horizon to be certified
and begin deliveries next year.
The aircraft unit is building toward
a strong recovery through
improved technology in product
and processes. When deliveries
begin, customers will receive a first
rate aircraft at an extraordinary
value. While the Horizon is an
advanced aircraft in every respect,
the composite fuselage and the
integrated utility system stand out
as two areas where technology
establishes an edge over the
competition.
Innovative Materials Make the Fuselage Lighter and Stronger
Raytheon Aircraft Company (RAC) leads the general aviation industry in composite technology and manufacturing. Radically innovative ideas in material processing, such as advanced
composite technology, typically take more than 30 years to mature into viable products.
Composite structure for airplanes was first introduced at Raytheon Aircraft, formerly Beech,
about 20 years ago. Today, composite technology has already gained wide acceptance in
the marketplace providing a competitive advantage over conventional aluminum structures.
The Premier 1, the first FAA certified business jet manufactured by RAC featuring a composite fuselage shell, is currently being delivered to customers. Several years before the
first delivery, more than 150 Horizons have been ordered. Composite materials offer these
advantages in airframes:
• Reduced weight and increased volume – A composite fuselage weighs about a third less
than similar metal structures, yet is three times as strong as steel. It also offers more
internal volume than metal fuselages with the same outside diameter by eliminating

the need for stringers and longerons that hold metal airframe skins in place.
• Faster production and reduced construction costs – Automated manufacturing of an
aircraft fuselage through computer controlled machines reduces production time
and cost. Computer aided three-dimensional interactive application (CATIA) data is
passed directly to the Viper™ made by Cincinnati Machine, which winds the fibers
around the mandrel. This replaces previous processes where Engineering passed
drawings to Manufacturing, who then had to figure out how to build it.

• Reduced maintenance – Compared to aluminum, composites are highly resistant to
fatigue and corrosion. Repairs to damaged airframes are also comparatively simple.
• Improved construction process – The reliability of automated manufacturing through

the interior equipment before being mated to the others. To make the three pieces, an
aluminum mandrel that defines the inner shape of the fuselage is mounted on the Viper™.
The Horizon cockpit accommodates a crew
The Viper™ is a seven-axis computer controlled fiber placement system that places up to
of two, with controls located to provide
24 one-eighth inch wide “tows,” or fibers of carbon graphite composite material. This is
convenient operation for a full range of
equivalent to a three-inch band. Fibers are placed at speeds up to 1,800 inches per minute
with an accuracy of 0.005 inch (Figure 1).
Once the inner layer is complete, a layer of Nomex™ honeycomb is placed over it (Figure
2). These core pieces are cut by a Numerically Controlled (NC) milling machine and located
on the mandrel by laser projection for a near-perfect fit. A foaming adhesive fills any small
gaps, then a final outer layer of graphite composite material is laid on the honeycomb.
The assembly is then placed in the outer mold shells to define the outer fuselage skin profile. When forming is complete, the mandrel is removed, and the assembly is placed in one
of the world’s largest autoclaves to cure at a temperature of 350ºF for eight hours. During
the cure, the autoclave is pressurized, but a vacuum is drawn on the tool to cause the part
to press against the outer mold shells.

Digital Engine Operating System (DEOS) - The Operating System
The operating system managing network activity is the Digital Engine Operating System (DEOS). DEOS is a Real-Time Operating System
(RTOS) designed by Honeywell specifically for safety critical applications. It provides Windows NT-like services to program applications and
has been certified to a Level A design assurance standard.
DEOS manages computing resources including processing time, physical memory, I/O and interrupts. In addition, it manages kernel
resources such as processes, threads, semaphores, mutexes, events and mailboxes. For most resources, DEOS provides two mechanisms
for allocation: guaranteed (the resource is guaranteed to be available) and best effort (the resource is allocated if available). Resources
essential to safe operation are thereby guaranteed to be available while allowing non-essential activities to proceed.
DEOS services are deterministic. For example, the allocation of slack time can only be made when doing so will not jeopardize the ability
of the DEOS to meet all future guarantees. This requires scheduling determinism. DEOS uses preemptive fixed priority scheduling (also
known as rate monotonic scheduling). The time required to execute DEOS services is also deterministic. DEOS also has built-in features
for integrity monitoring. This includes Built-In Test (BIT) for Random Access Memory (RAM), memory addressing and interrupt handling,
and a cyclic redundancy check on Read Only Memory (ROM).
The combination of superior materials and an advanced concept of systems integration makes the Hawker Horizon unique. Product
delivery will restore Raytheon Aircraft to preeminence in aviation.

CROSS
TECH on COMPOSITES
panel discussion
Cross Tech – Crossing business boundaries, promoting collaboration and knowledge sharing an internal panel discussion with Raytheon experts on one of Technology Today’s featured technologies.
Scire: “Today we will be discussing
composite structures, not only their
role in the Hawker Horizon, but also
their usage across the company. We
have a great group of composite
experts with diverse backgrounds,
including design, materials engineering,
structural analysis and manufacturing.
We will be discussing key aspects of
composites, selection and usage in the
design, manufacturing concerns and
lessons learned. Bill Fossey from
Lexington, Mass. will be leading the
discussion.”
Fossey: ”First, let’s discuss design
advantages in composites. They should
be considered during the initial design
trade studies in order to deploy them
most effectively. What do you think
the design advantages of composites
are and how do they apply to your
businesses, since each of us is different
as to where we apply composites
technology?”
Sears: “Obvious factor is weight, primarily
in structures, fin structures, wing structures.
Also, we design and manufacture a lot of
radomes and composites, it’s an economic
material to use. In some cases it’s weight,
sometimes it’s economy versus the alternative (ceramics). It’s pretty versatile to produce. There are a lot of shapes and things
like that you can use. Composites are also
tailorable in terms of electrical properties,
mechanical properties, you can change the
fibers, and you can change the resin. But it
has to be treated as a system, you have to
pick the right material for the right design
and application.”
Mijares: “I think you have to step back
before you say composites and look at the
requirements. What requirements are you
trying to fulfill? The requirements should
drive the material selection for the design.
I’ve seen great metal parts made out of
composites. So first things first, you have
to have a set of requirements. Then you
go through a series of trade studies that
lead to a materials selection and a form
that best meets those requirements at the
lowest manufacturing cost. If you can
make those four things converge; requirements, materials, material form, and
manufacturing cost, then you have a point
design solution that is about as good as
it gets.”
Splichal: “Our main objective we had
with the aircraft was not only go for
weight but also reduce part count and
using composites resulted in a tremendous
reduction of parts. If you take the
Raytheon Aircraft, Beech Jet, which is your
conventional aluminum construction that
has the aluminum skin with stringers and
frames, we have 50 percent fewer parts
because of composites on Premier 1 than
Beech Jet. The labor content is many times
lower, and also the weight. We’re about
one third the weight of a Beech Jet, and in
addition to not having all of these frames,
stringers that you would normally have in a
conventional aluminum construction the
cabin ends up becoming larger, which is
advantageous in the market we have. We
are trying to sell an aircraft that has the
lowest possible weight that provides the
customer with the best performance. At
the same time, we don’t want to compromise the comfort in the cabin, because
that is the type of customer base that we
sell to. We are competing with our competitors and what they’re selling is performance and comfort. Premier I – it is the

worked and what needs help…before you
go down a path that is going to require
some back fixing.”
Fossey: “Mike, would you like to
comment on how you tie manufacturing into the design process?”
Meek: “Most of it is internal to our
McKinnery database. We custom tailor
IPDS to fit the needs of the particular
program.”
Meek: “In McKinney, we have a complete
design community. The Composites
Engineering Team (CET) works with the
marketing groups and pursues new markets that can provide the best solution to
some of the technical difficulties that we
talked about before in shape and molding
and reducing part count. Typically an
Integrated Product Team (IPT) comes
together, and on that team, we have
someone from marketing, manufacturing
and producibility, the CET, and electrical
engineering. Once the requirements are
determined, this IPT team submits a plan to
transform design to a production product.
One of the tools that is utilized to improve
efficiency is the IPDS system.”
Scire: “Have you incorporated any
of your lessons learned into IPDS or
is that just internal to McKinney?”
Sears: “We also are co-located so everyone can talk to each other conveniently.
Problems can be detected and resolved
quickly and easily.”
Mijares: “The 450 program was our first
full airplane program that we kicked off
ground up on IPDS. We got started
in the discussion of material structure
optimization, selection, manufacturing
methods, and producibility in the early
design stages, in IPDS terms, Gate 2. It is
absolutely essential for any design for any
system to get manufacturing input in as
early as possible. Designers define the cost
of any structure. Up to 95 percent of the
cost is locked in before you get to PDR
(producibility design review). Better do your
homework upfront and work real hard to
find the cost effective form that will fit the
function before you get to PDR, because
after PDR, you’re executing a design concept. You’re essentially filling in the blanks
and doing the detail work and the cost of
a change after PDR can be astronomical
compared to pre-PDR.”
Meek: “What makes this beneficial is that
we have databases, in a shared drive,
where all of the lessons learned are shared
across the whole community. When you
work on a design you can refer to what has
Meek: “The value of IPDS is that it ties
together business development, program
management, product design and development, all the way back to supply chain
management. It enables you be pro-active
in your planning and instead of reactive to
problems that pop up.”
Sears: “Having gone through multiple
gates, it actually is a very worthy and
worthwhile thing to do. It’s a good check
and balance. The process makes you ask
the right questions. Very important to do
in order to make a program right.”
Fossey: “When you do your initial
trade studies and get your requirements and start to flow them down,
it is at very top level that you decide
which way you’re going to go, which
materials you will use and basically put
this whole assembly together, such that
you’ll achieve your functional requirements. That is when you’re already
starting to make decisions on how an
assembly is going to be made, how the
pieces are going to tie together and
what your integration costs are going
to be.”
Mijares: “Right as you make the decision
on what materials to use, you just made
cost decision, and the same goes for
manufacturing methods.”
Neal: “Early in the design phase you need
to pull in the analysis guys and make sure
they have input to that as well. It is
extremely important that you do not ever
overestimate the importance of doing your
homework.”
Seiferman: “If you are going to design
similar products over and over again, it is
best to have a well defined process - IPDP

does this for us. Also, having a set of best
practices for a composite design team to
utilize is desirable.”
Fossey: “Addressing tooling design
and part design. Point out the relationships between our design practices
and how tooling actually plays into
the part design.”
Mijares: “Tooling is part of the manufacturing flow of a part when we do
producibility review. You have to consider
the part design (what are the critical
dimensions, what material is the part made
from), the part form (what are the critical
design characteristics, tolerances, finishes),
the target part cost/rate in the context of
the capabilities of your plant, your equipment, your facilities and feed that back
into the design. It’s not a trivial pursuit.”
Neal: “Very small seemingly insignificant
characteristics of parts can sometimes drive
major tooling or manufacturing concept
changes.”
Seiferman: “Part quantity definitely
drives what tooling approach that you
use. Resin transfer molding (RTM) is a
very good way to get the cost down. But
the number of parts you’re going to build
plays a significant role in the tooling
approach and into determining what is
lowest cost approach to produce
composite parts.”
Splichal: “RTM has really driven the cost
down on the Premier I flaps.”
Sears: “Within the McKinney CET group,
it is not unusual for the designer to also
do the tool design in addition, to integrating the tool design into the actual design.
It has been very successful, particularly in
the RTM shop.”

winter 2002
(continued)
Meek: “From a manufacturing standpoint, we make a lot of symmetrical part
radomes so you always want to integrate
your tooling where you have a home
position. To facilitate post process diagnosis, you need to know where your materiallayer pedigrees are from. Manufacturing
must control all the significant variables as
the process or part is being molded or
generated. If you don’t understand the
variables of each process level, then conducting process diagnostics will be
extremely frustrating.”
Fossey: “Expand on manufacturing
variables…how do we gather data
off the line, how do we feed that back
into the process data and how does
that bump up against the processing
database that we had to begin with.
How do you drive that back in? How
do you monitor your SPC points during
development?”
Mijares: “What is important is what are
the critical variables…then you have to
look at what you’re doing in order to
establish your tracking plan. The real
problem lies in having critical variables that
you can control before you cure the part so
that you can ensure success, because once
it’s cured, it’s too late. During the cure
cycle, you have to make sure the cure
profile meets the critical variable requirements for cure in terms of pressure and
temperature, so that it ensures part
success within its process limits.”
Splichal: “There is always going to be
variability, at least in the structures end. We
have to have an extensive materials testing
program to explore the full extent of the
variability plus come up with allowables
and design parameters for the materials.”
Fossey: “Any comments on databases in general and how they may
constrain your design choices as well
as free them up?”
Neal: “It’s really the cost of obtaining
the data that’s a constraint, not the data
itself.”
Sears: “You have to very careful
about your database and how you use
them…they are tools, not rules. They
are not there to dictate designs.”
Fossey: “How do you employ the data
you have in composite analysis? How
does that effect your part design?”
Splichal: “Pushing for building block
approach in which we perform material
coupon tests to determine the mechanical
properties. In the aircraft world, there are
also many environmental factors involved.
Basic coupon tests to drive the mechanical
properties, allowables, b-bases for the
cold/dry room temperature hot/wet, etc.,
and then from there some of our design
features.”
Fossey: “Any specific schedule
constraints to consider when using
composites in the design?”
Seiferman: “Having to perform a
material characterization effort can add
much time to a schedule and cost. Most
programs don’t want to pay for the
material certification, so we have to look
for ways to get the minimum amount of
information in the shortest time possible
and attempt to with low cost and little
time get maximum performance-out of
the materials.”
Splichal: “There is still a comfort towards
metal as opposed to composites. Analysis
of composites is many times more involved
than what you have with metals.”
Sears: “With composites you need to
plan it and produce it like an assembly.
There are many more processing steps
involved with composite fabrication and
assembly compared to metal designs.”
cross tech
Fossey: “Let’s discuss best practices
and how to benchmark yourself
internally and externally (crossfertilization).”
Mijares: “Problem with benchmarking
composites is the uniqueness in what you
do. There are some things that will be very
difficult to benchmark like our fuselage
shells, while others, like our hand lay-up
parts may be easier because they use more
common industry processes.”

Fossey: “Let’s wrap it up with a

not have a database for all the various
materials and processes including mechanical properties, and allowables and things of
that sort…and how much re-inventing of

Seiferman: “In the defense world
we would like to see better processes for

Meek: “As a program manager,

of lowering your operating costs.”

and we need to include all of the cost factors in our assessment, not just the upfront costs.”

Mikael K. Meek Presented With One Company Award
Mike Meek received a One Company
Award from Greg Shelton, VP of Engineering
and Technology, for his help in leading a
team of composite specialists across the company to solve porosity and yield problems at
Raytheon Aircraft Company (RAC). His one
company involvement meant spending the
better part of four months on the road
between Kansas and Texas. He has been
instrumental in leading design of experiments
and statistical problem solving in the pursuit
of process yield and quality improvements on
the Premier and Horizon programs. This
dedication was at the sacrifice of his home
organization and assignment.
Mike’s composites’ experience recently
proved to be a key team ingredient in solving
the line stopping porosity/delamination issues
at RAC in Wichita, Kansas. His composite
leadership, focus on statistical methods and
unique electrifying energy and humor (while
working long hours to solve the Premier
aircraft problems) were an absolute key to
Wichita’s current composite cost, schedule
and quality success. The composite team has
reduced porosity related rework hours on the
Premier Fuselage shells from over 20 percent
to as low as 4 percent.
The manufacturing area within RAC had
been suffering from low yield and high
rework on composite parts for some time.
The composite area is the key to our next
generation aircraft manufacturing. Without
our composite capability our Premier and
Horizon aircraft could not be manufactured.
Mike is highly recognized by peers, subordinates and management for his knowledge
and experience in controlling cost, schedule
and quality through his tireless efforts in
utilizing Raytheon Six Sigma (R6σ) and
Statistical Process Control (SPC) techniques.
His management and technical skills were
essential in assisting the composites’ teamwork across business units and functional disciplines. His R6σ expertise helped focus the
team at RAC on the step process improvements. “Mike is a great motivator of people,
Greg Shelton (right) congratulates Mike Meek (left)
on receiving his One Company Award.
he has the uncanny ability to get teams to
think outside of the box, and execute superior solutions. His positive impact helped move
the team forward" stated Phil Sears, a coworker from the Composites Engineering
Team (CET) in McKinney, TX who also
helped Mike at Raytheon Aircraft.

Excellence in Technology
Distinguished Level Award Winners Announced
T
he Raytheon Award for
Excellence in Technology is
the enterprisewide award established to provide visible, tangible
recognition and reward for technical
achievement among key contributors, both individuals and teams. An
executive selection team selected
those to be honored by the enterprise with the Distinguished Level
award. On April 10, nine individuals and 15 teams will be recognized
with the Raytheon Distinguished
Level Award for Excellence in
HRL LABORATORIES
Development of High Power Solid-State Lasers
Hans Brusselbach
Contribution Description: Solid-state lasers
have many uses for the military systems
that Raytheon builds and hopes to build.
Many applications require more and more
power output from the laser. In the laser
materials, along with light, undesirable
heat is also generated. This has deleterious
effects on the performance of the laser.
Many years ago Brusselbach realized the
advantages of a new solid-state laser material, Ytterbium doped Yttrium Aluminum
Garnet over the widely used Neodymium
doped Yttrium Aluminum Garnet.
Brusselbach came up with innovative ways
for efficient cooling and excitation of the
laser material. Through a series of modeling, design, building, testing, and improvement cycles, Brusselbach has continuously
increased the laser power output from 69W
of the first demonstrator unit to the latest
2.65 kW world record. These results confirm the power scalability of Ytterbium
doped Yttrium Aluminum Garnet laser,
and it is the highest power output from
a single laser rod.

Ground Surface Deformations
Zhong Lu
COMPANY
Contribution Description: Subtle changes or
shifts in the Earth’s land surface (i.e., surface deformation) can have critical short14
winter 2002
and long-term consequences for a given
region. Surface deformations are of great
interest to the geological community; more
importantly, they show promise as
a potentially life-saving early warning
system for volcanic eruptions and as a
source of critical information related to
ground-water availability and recharge.
Dr. Lu has been instrumental in developing
and applying techniques to map and
measure land surface deformation across
the Earth’s landscapes using satellite data.
Using interferometric analysis of imagery,
from the synthetic aperture radar
instruments aboard European Space
Agency satellites, he has developed and
refined techniques to generate maps
that depict surface deformation.

Raytheon’s Engineering and Technology Councils
Fostering Internal Collaboration & Communication
H
ow do our engineering and technology leaders communicate, collaborate,
and share best practices and lessons learned across the businesses at
Raytheon?
In 1998, the engineering and technology leaders decided to form a cross-segment (SES,
DSS, C3, IS, AIS of the former Raytheon Systems Company (RSC)) council and called themselves the Engineering & Technology Council (E&TC). Their purpose was to unite our company’s engineering communities, bringing the "best of the best" together, and promoting
a one-company philosophy. This very successful concept continued as Raytheon Company
transformed from Segments to Businesses. Dr. Phil Cheney, the then VP of Engineering
(now retired), decided to raise the level of the E&TC to a Raytheon Company body. In
doing so, he included the newly formed businesses (ES, C3I, AIS, RTSC, RSL, and RCE).
The E&TC continues on, now chaired by Greg Shelton, VP of Engineering and Technology
for Raytheon Company, and is comprised of the engineering vice presidents from each
business along with the corporate engineering and technology staff. The E&TC is a business-centric engineering and technology leadership council that communicates, collaborates, and shares best practices and lessons learned across the businesses. To leverage our
size and diversity, the E&TC has established the Raytheon Engineering Common Program
(RECP) that enables and facilitates common initiatives. Some of these common initiatives
include: IPDS, Technology Networks, engineering collaboration and engineering communication. In addition to RECP, the E&TC has four councils that report to them. They are the
Engineering & Enterprise Council (E&EC), the Engineering IPDS Council (EIC), Technology
Leadership Council (TLC) and the Engineering Automation Council (EAC).
The E&EC consists of leaders from each of the nine engineering discipline councils (ECs);
Aeronautical Engineering Council (AEC), Analog, RF, and Microwave Engineering Council
(ARMEC), Configuration Management, Data Management Engineering Council (C/DMEC),
Digital Electronics Engineering Council (DEEC), Electro-Optics Engineering Council (EOEC),
Mechanical Engineering Council (MEC), Product Development Center Engineering Council

includes the Engineering Automation
Council (EAC) and enterprise council chairs
or representatives; from the Program
Management Council (PMC), Quality
Council (QAC), Supply Chain Council (SCC),
and Business Development Council (BDC)
to improve enterprise collaboration.
The EIC is comprised of process and tools
directors from each business, enterprise
council representatives, two engineering
council chairs, the RECP Manager, and the
EAC Chair. The mission of the EIC is to
improve competitiveness through leadership in engineering process and tools
associated with the design, development
and integration of core processes and
sub-processes specific to our enterprise,
specifically IPDS. John Gatti, Director of
Integrated Product Development and
Raytheon Engineering Common Program
manager, chairs both the E&EC and the
EIC.
The TLC is comprised of the business technology directors under the leadership of
Doc Dougherty, ES Technology Director.
The TLC advocates technology within
Raytheon, coordinates IR&D strategies
and plans, and integrates the university research program with IR&D.
Additionally, the TLC provides
guidance to the Technology
Networks under the direction of
RECP.
The EAC is comprised of the
managers of Engineering
Automation and Computing
from each of the businesses
and major sites. The mission of
the EAC is to provide a mechanism for communication and
coordination among EA operations
throughout Raytheon. The EAC

The Engineering discipline councils continue
to provide a means for collaboration and
communication across Raytheon. In 2002,
the councils are chartered with developing
competency models to enhance career
development and learning, IPDS vertical
alignment and maintenance, and continued
support to the Technology Networks. The
councils, populated with leaders representing the full range of geographic locations,
functional organizations and programs, are
one of our best resources to promote our
aspiration to be the best in our industry,
utilizing the advantage of our size and
diversity while providing superior technical
solutions.

Raytheon, we encourage people to work on technological challenges that keep
America strong and develop innovative commercial products. Part of that process is
identifying and protecting our intellectual property. Once again, the United States Patent
Office has recognized our engineers and technologists for their contributions in their
fields of interest. We compliment our inventors who were awarded patents from October
to December 2001.
Low Cost Antenna Pointing System, patent 6317093
T
he Low Cost Antenna Pointing System, patent 6317093, is a product designed to
quickly point commercial antennas used in two way geostationary satellite communication
systems, typically called broadband systems. Unlike typical DBS systems (such as Direct TV)
licensed professionals must install two-way systems because they transmit. Also, because the
systems transmit at significantly higher frequencies than they receive, an antenna can be
adequately positioned to receive data from the satellite, but actually be off the satellite by a
degree or more. This is because the receive signal is effectively flat in its center region and the
maximum reading is easily affected by fluctuations in satellite signal, atmospheric fluctuations
and other effects. For current installations, installers typically verify their pointing accuracy by
calling up the hub and checking what their transmission data rate is. If it is high enough, the
satellite is adequately pointed, if not, the technician repositions the antenna and tries again.
Installers are finding this to be a time consuming process.
Transmit Signal
Receive Signal
Center region
The low cost antenna pointing system
is able to position the antenna very
accurately by using only the receive signal.
Instead of just finding the peak signal
position (which is subject to errors as
described above) it sweeps over a range
of signal. Because signal strength is
effectively parabolic versus angle in its
center region, the system takes a data
sweep and then mathematically finds the
center by curve fitting. The error in any
given data point is minimized.
The major items in the pointing system are two actuators that automatically sweep and
position the antenna in elevation and azimuth, respectively, a microcontroller that records all
the data, does the curve fitting and runs the actuator motors, a signal measurement module
and a power system. The system packages into a small case and is powered by rechargeable,
commercial power tool battery units. Raytheon is currently marketing the system as the
Beamtrac. Information and a video demonstration can be found on the external website:

The Reeder Compensator is a device that
compensates a rod's thermal birefringence
using reciprocal optics instead of a Faraday
rotator. This eliminates the depolarization
problem and allows one to substantially
improve the beam quality of strongly pumped
solid state lasers, with a fairly minor change in
the resonator design.
Robin Reeder is a laser physicist that has
worked at Raytheon since 1978, after
graduating from CSUN with a masters degree
in physics. His primary interest is in the field
of physical optics, that part of optics that
isn't about ray tracing, a field in which he
has ten patents.
Intensity
At
The Reeder Compensator, patent 6317450,
is an invention in the field of solid state laser
physics. A laser is a coherent light source that
requires, first, a gain medium, second, a way
of producing gain in
the medium, since the
medium is not naturally
in a gain state, and
third, feedback, since
many passes through
the gain medium are
necessary to produce a
directional high energy
beam. It is the second
step that is of concern
Robin Reeder, inventor of the
here, because producReeder Compensator
ing gain, via optical
pumping, generates heat that must be
removed. Cooling of a cylindrical laser rod
causes a radial thermal gradient within the
rod, producing stresses that cause thermal
birefringence, a complex depolarization
pattern greatly degrades beam quality.
