Output pulse duration depends on wavelength and pump laser pulse duration. 3) I-OPA-F outputs broad bandwidth pulses which are compressed externally. 1) 2) I-OPA-CEP Up to 100 kHz Pulse energy, µJ I-OPA is an optical parametric amplifier of white-light continuum pumped by the PHAROS laser. This OPA is focused on generating long-term stable output with reliable and handsoff operation. Manually tunable output wavelength extends the application possibilities of a single laser source, instead of requiring multiple lasers based on different technologies. In comparison to standard ORPHEUS line of devices, the I-OPA lacks only computer controlled wavelength selection. On the other hand, in-laser mounted design provides mechanical stability and eliminates the effects of air-turbulence, ensuring stable long-term performance and minimizing energy fluctuations.

For example, a PHAROS-20W laser at 50 kHz (400 µJ energy) will increase the output power twice, and the pulse energy – 4 times compared to the reference table above. The pulse duration at the output is <300 fs in all cases. The OPA output is not limited to these particular ranges of operation, it is continuously tunable as shown in energy conversion curves. 62 30 30 114 Optical parametric amplifiers 85 70 125 212 Idler Signal Residual OPA pump (515 nm or 1030 nm) Optional Uncompressed Fundamental (for SHBC) Fundamental (1030 nm) TOPAS devices Pharos with I-OPA output ports 430 691 1070 PHAROS with I-OPA-F and compressors for signal and ilder Spectrometers (39) Oscillators Our solution Autocorrelators Laser technology Harmonics Generators Comparison with other femtosecond and picosecond lasers Industrial Lasers Industrial Lasers 9 Femtosecond Laser for Industrial and Medical Applications FEATURES We offer CARBIDE industrial femtosecond laser. Featuring output power of >5 W at 1028 nm wavelength, with highest pulse energies of >85 μJ, it maintains all the best features of its predecessor PHAROS: variable pulse repetition rate in the range of 60–1000 kHz (amplifier internal clock) with the built-in pulse picker feature for pulse output control, computer controllable pulse duration 290 fs – 10 ps. In addition to usual parameters CARBIDE brings in a few new technologies. One of the most important being a few times higher output average power to wall plug efficiency. It also features novel approach to a cavity design where oscillator, stretcher/compressor and amplifier are integrated into a single housing, this way optimized for volume production. It also allows fast warm-up (important for medical applications), easy access to pump LD modules for replacement. Intra-cavity pulse picker allows reduction of cost and power consumption. Highly integrated LD driver and control electronics, along with embedded control computer now provide less electromagnetic noise emission and allow faster assembly during production stage. However, one of the most <290 fs – 10 ps tunable pulse duration >85 μJ pulse energies >5 W output power 60 – 1000 kHz flexible repetition rate Includes pulse picker for pulse-on-demand operation Rugged, industrial grade mechanical design Air or water cooling Automated harmonic generators (2H, 3H, 4H, 5H) impressive feature of CARBIDE is its size of 631×324×167 mm including integrated power supply and air cooling unit. This represents about 7 times reduction in system volume as compa red to PHAROS, already one of the most compact ultrafast lasers on the market. CARBIDE features number of optional components comple menting different application requirements: certified safety shutter, beam conditioning unit (beam expander with optional spatial filter), automated attenuator, harmonics unit, additional pulse picker for enhanced contrast. CARBIDE is primarily targeted to the industrial market where relatively low average power cost effective solution with ultrafast pulses is needed. In largest part this is biomedical application with a direct biological tissue processing or biomedical device manufacturing. In addition output parameters of CARBIDE are sufficient to support different wavelength converters starting with harmonic generators to parametric amplifier.

Oscillators References Autocorrelators APPLICATION IN MICROMECHANICS 17 Ultrafast Yb Oscillator FEATURES Autocorrelators 18 First choice for seeding of Yb based ultrashort pulse amplifiers Excellent pulse contrast due to the high nonlinearity inherent for optical Kerr effect High output power up to 6 W (pulse energy up to 75 nJ at 76 MHz) Ideal source for broadband THz generation Spectrum bandwidth is broad enough for seeding simultaneously Yb and Nd based laser sources in OPCPA systems Optional CEP stabilization Possibility to lock output pulse phase to external clock Sub-80 fs pulses directly from the cavity of the laser without any additional external pulse compressors The oscillator module is machined from a single monolithic aluminium block which is cooled by water to ensure stable and robust operation. The oscillator housing has two seperate sections: cavity section and pump module section on the opposite side. Detector module, which includes a photodiode for oscillator power monitoring, is attached to the front side. The oscillator is contained in an external casing in order to reduce the performance impact of enviromental temperature changes. The special design of the external casing includes three point kinematic mounts which are used to support the oscillator preventing any mechanical stress caused by differences of thermal expansion between the optical table and the laser housing. The FLINT oscillator is based on Yb:KGW crystal end-pumping by high brightness laser diode module. Generation of femtosecond pulses is provided by Kerr lens mode-locking, which is induced by perturbation of the cavity length. Once started, modelocking remains stable over a long period of time and is immune to minor mechanical impact. The oscillator can be equipped with external electrooptical Pulse Picker and appropriate timing electronics allowing selection of a single pulse at repetition rates up to 100 kHz. Piezo-actuator can be implemented in customized oscillators in order to control the cavity length. FLINT oscillator can also be equipped with Carrier Envelope Phase (CEP) stabilization system.

We offer several standard HIRO models (with open prospect of future upgrades) which meet most users’ needs.

It can be easily modified to provide white light continuum, beam splitting/expanding/ down-collimating options integrated in the same housing as well as harmonics splitting that makes all three harmonics available at a time. The principle of HIRO operation is based on collinear generation of higher laser radiation harmonics in angle-phase-matched nonlinear crystals. The optical layout of HIRO also includes beam reduction and collimation optics that ensures highest harmonics conversion efficiencies. Usually one active harmonic can be selected from HIRO, however the residual lower harmonics can be also accessed through the output ports. All the accessible harmonics exiting HIRO are already separated from the lower ones by dichroic mirrors.

This OPA combines the short pulse durations that are produced by a non-collinear OPA and wide wavelength tuning range offered by collinear version. Parametric amplification is performed in two stages. The first nonlinear crystal (BBO) is non-collinearly pumped with the second harmonic of pump laser at 515 nm and seeded with a white light continuum, producing broad bandwidth tunable output in 650 nm – 900 nm wavelength range. The second nonlinear crystal (type 1 BBO/LBO) is again pumped by the SH of pump, but in a collinear configuration. The output of the second stage is a Signal wave tunable in the range of 650 nm – 900 nm, and corresponding Idler at 1200 nm – 2500 nm. Both beams exhibit a broad spectrum, with typical bandwidth reaching 300 – 600 cm-1 at some wavelengths. The Signal beam can be easily compressed with a simple prism-based setup down to <60 fs in most of the tuning range, while Idler is compressed in bulk material down to 40 fs – 90 fs depending on wavelength.

The first nonlinear crystal (BBO/LBO) is pumped with the second harmonic of pump laser at 515 nm and seeded with a white light continuum, which generates a very stable tunable output in two ranges: 650 – 850 nm (first stage signal) and 1350 – 2100 nm (first stage idler). The second nonlinear crystal (KTA) is pumped by the fundamental pump radiation at 1030 nm, and seeded with the idler of the first stage. The output of the second stage is a Signal wave tunable in the range of 1350 – 2060 nm, and corresponding Idler at 1450 – 2060 nm. In comparison to standard ORPHEUS + DFG configuration, the ORPHEUS-ONE provides higher conversion efficiency into the infrared range due to the pump energy available for the KTA crystal. Up to 80% of pump radiation is used in ORPHEUS‑ONE, while the OPA+DFG can only use about 40% of the pump. Furthermore, ORPHEUS-ONE integrates the two stages into a single housing, which minimizes the footprint of the system and increases the long term stability. The extended range 4500 – 16000 nm is accessed by mixing the signal and idler of the second stage in a mid-IR crystal (Gallium Selenide). By comparison, in the standard OPA+DFG 1000 Signal and idler tuning from 1350 nm to 4500 nm Tuning range extendable to 16000 nm Twice the output in mid-IR compared to standard ORPHEUS Built on well-known TOPAS OPA basis Repetition rate up to 1 MHz Bandwidth limited or broad-bandwidth configurations available Adaptable to different pump pulse energy and pulse duration Full computer control via USB port and dedicated software configuration this range is accessed by mixing fundamental 1030 nm with idler of BBO crystal (1100 – 1350 nm). This method greatly limits the output bandwidth of the output, producing only 40 – 80 cm-1 in the mid-infrared. The scheme used in ORPHEUS-ONE can generate >150 cm-1 when OPA is configured for broad-bandwidth amplification.

For highest time resolution, fluorescence is measured using upconversion technique, where the fluorescence light emitted from the sample is mixed in a nonlinear crystal with a femtosecond gating pulse from the laser. The time resolution is then limited by the duration of the gate pulse and is in the range of 250 fs. For fluorescence decay times exceeding 150 ps, the instrument can be used in time-correlated single-photon counting mode that allows for measuring high-accuracy kinetic traces in the 200 ps – 2 μs domain. Chimera is designed around the industry leading Becker& Hickl® time-correlated single-photon counting system, with different detector options available. The combination of two time-resolved fluorescence techniques enables recording the full decay of fluorescence kinetics at each wavelength; with full data available, spectral calibration of the intensity of kinetic traces taken at different wavelengths is possible, where the integral of time-resolved data is matched to a steady-state fluorescence spectrum. High repetition rates of Pharos laser system allows for measuring fluorescence dynamics while exciting the samples with extremely low pulse energies (thereby avoiding exciton annihilation effects in energy transferring systems, or nonlinear carrier recombination in semiconductor/nanoparticle samples).

One arm of the fundamental pulse is delayed by means of a high-resolution 5-phase stepping motor, at 3 fs for full step this resolution can be further enhanced up to ten times by means of step division integrated into electronics and software. The beam to Autocorrelator is directed with the periscope which can be arranged in either polarization-maintaining or polarization-rotating setup, allowing easy measurement of vertically or horizontally polarized pulses. The beam is then Measures pulse duration in 10 fs – 10000 fs range Measures wavelengths down to 500 nm and up to 2000 nm Compact and portable design Pulse-analysis software for pulse duration measurements split by a broadband metallic beamsplitter, and both beams are directed to a concave mirror, which focuses and combines the beams into a nonlinear crystal, producing a sum-frequency signal of two beams. The intensity of generated sum-frequency is directly related to temporal overlap between two fundamental pulses. By varying the timing difference with a stepping motor Geco can acquire a full intensity autocorrelation trace of 10 fs to 10 ps pulse duration. There are four filters and two nonlinear crystals available to cover the full 500 nm to 2000 nm range. Filters are placed on an easily changeable wheel with magnetic fixing.

Its unique design allows monitoring and measuring of the pulse duration as well as the pulse front tilt in both vertical and horizontal planes. TiPA is a straightforward and accurate direct pulse-front tilt measurement tool. Operation of TiPA is based on non-collinear second harmonic (SH) generation, where the Measures pulse duration in 30–1000 fs range Measures pulse-front tilt Working range – from 500 nm up to 2000 nm Easy to align and operate Compact design Hi-speed 12-bit CCD camera User friendly pulse-analysis software spatial distribution of the SH beam contains information on the temporal shape of the fundamental pulse. This technique combines low background and single-shot measurement capability. The basic idea is that two replicas of a fundamental ultrashort pulse pass non-collinearly through a nonlinear crystal, in which SH generation takes place. SH beam’s width and tilt in a plane perpendicular to propagation provide information about the pulse duration and pulse front tilt. The SH beam is sampled by the included CCD camera. TiPA comes with a user friendly software package, which provides on-line monitoring of incoming pulse properties.
