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.
