FREGAT. Cr:Forsterite Femtosecond Amplifiers
|Pulse duration (FWHM)||<120 fs|
|Wavelength (fixed)||1240±10 nm|
|Output pulse energy*||>0.2 mJ||>0.6 mJ||>1 mJ|
|Required pump pulse energy (1064 nm, <200 ns)||10 mJ||35 mJ||50 mJ|
|Pulse repetition rate**||1 kHz||10 / 50 / 100 Hz||10 / 50 Hz|
|Output polarization||linear, horizontal
|Utility specs||100-240 V, 50 Hz|
|* - up to 30 mJ upon request; also see the FREGAT-TW system (110 mJ);
** - depends on the amplifier pump laser; an additional pulse slicer may be added to the unit. This improves the contrast ratio and allows the repetition rate to be adjusted from single-shot to the maximum repetition rate of the amplifier.
Globally the FREGAT family of Cr:Forsterite femtosecond amplifiers are to our knowledge the only commercially-available solutions based on this unique active medium. The systems radiate fs pulses around 1230-1240 nm. A standard FREGAT system generally includes a pulse stretcher, a regenerative amplifier, synchronization and delay generator, a pulse compressor, an integrated seed oscillator with a fiber pump laser and an amplifier pump laser. Single-box all-in-one optical head design allows robust operation and space saving.
Customized systems with peak power >1 TW are available upon request.

We have ramped up the maximum available output power for the TiF-100 series to more than 3 Watts at 800 nm, 100 fs, 80 MHz. The tuning range has also been extended to 720-950 nm, while an optional modification that covers 850-1040 nm is also avaiable. The system features a high-power low-noise integrated DPSS laser […]
TiF-100ST-F6 femtosecond Ti:S oscillator with Frep locking for multiphoton microscopy at CANDLE, Armenia
The TiF-100ST-F6 femtosecond Ti:S oscillator with a built-in pump laser, also equipped with the ALock PLL electronics unit for pulse repetition rate locking to an external RF source has been installed at the Synchrotron Research Institute’s CANDLE facility in Armenia. The setup has been developed and commercialized during the joint Russia-Armenia project supported by FASIE (Innovation […]
