DM Ti:Sapphire Pumping Advantages
The DM Series is optimized for Ti:Sa pumping and easy integration into UF amplifier systems. It has the
highest power and pulse energy in Green wavelengths for higher Ti:Sa output. Its smooth beam profile allows
for homogenous illumination of the Ti:Sa crystal rod and the narrow pulse width gives a high peak power. The
DM lasers are extremely stable with a long term energy stability of <1% which contributes to better stability in
Ti:Sa amplifiers. Their user-friendly control interface and proven reliability with OEM customers make the DM
Series lasers an exceptional choice for Ti:Sa pumping.
DM PIV Advantages
The single head DM lasers offer a dual pulse feature and have proprietary driving electronics to control
pulse separation and delay. The dual head option for sub ns pulse separations.
Our high power, kHz DPSS lasers fit in a niche termed “High-speed PIV”. This relates not to particle flow,
but the speed of image acquisition. High speed cameras and powerful computers have allowed the transition to
higher repetition rates. Many customers with 10 Hz PIV lasers may be interested in upgrading to a kHz system.
OPO Series
High Repetition Rate OPO Diode
Pumped Lasers
Photonics Industries developed the first, commercially available, diode pumped, high repetition rate
Optical Parametric Oscillator (OPO). The foundation is built on PI’s field proven DS Series Nd:YLF laser platform
operated at low kHz pulse rates which uses PI’s patented intracavity frequency conversion technology.
The OPO Series advantage of intracavity frequency conversion includes high conversion efficiency (typically 2X conventional) as well as better pulse-to-pulse and average power stability. The high intracavity pumping
intensity makes high repetition rates (kHz) possible from a compact package.

SLM/NL Option
Single Longitudinal Mode (SLM) and Narrowed Linewidth (NL) Lasers
High Power/High Rep Rate SLM and NL Lasers
The difference between the Siingle Longitudinal Mode (SLM) and the Narrow Linewidth (NL) options is the coherence length. NL gives coherence length ~2cm while the SLM gives a coherence length of
~20cm. NL is typically more suitable to industrial applications than the SLM option.
Photonics Industries’ NL lasers come in a variety of configurations including DC, DP and DS based.
The SLM lasers are only based on our DS and DP platforms.
SLM options are available for many of Photonics Industries’ fixed wavelength ns laser models as follows:
••SLM (option A) – linewidth <100MHz
••SLM (option B) – linewidth ~1GHz
••Narrow Linewidth ~3GHz (which is ~10% of
standard fixed ns lasers linewidth) or long coherent
length ~10 x standard Q-switched laser PI Patent on
NL technique
These linewidth measurements are for the fundamental wavelength. As the wavenlegth moves into the
harmonics, the linewidth naturally broadens.
SLM and NL Applications
••Single Longitudinal Mode (SLM)
••Lidar
••High Spectral Resolution LIDAR (HSRL)
••Wind LIDAR
••Coherent Doppler LIDAR (aka Coherent LIDAR) heterodyne detection
••Incoherent Doppler LIDAR (aka direct detection)
••Narrow Linewidth (NL)
••Holography
••generally performed with cw lasers, it is possible to get
pulsed lasers to work if the coherence length is maintained
over the pulse train
••pulsed SLM lasers are good for motion holography
••holographic 3D imaging
••3D PIV hologram research (volumetric PIV)
••Multiwavelength SLM lasers have been used in LIDAR measurement and characterization of the particulate emissions from
agricultural production.
••Narrow linewidth or SLM lasers are of interest for Differential
Absorption LIDAR (DIAL) to precisely identify trace chemical species

DP YAG for Dye Laser Pump Retrofit Market
The short pulse width of our DP is ideal as dye laser pumping needs the peak power. Most
dye lasers today are pumped at ~10Hz. However, if a good pump source was identified, kHz rep rate
can grow due to interest in increasing the rep rates for increased data acquisition speeds.
Today untrafast (fs) research is all done in the ground state. Kilohertz dye lasers could enable excited state atomic research!
