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.

Avesta is participating in Ultrafast Phenomena 2018 conference and tabletop exhibition in Hamburg, Germany (15-20 July). We would be glad to discuss any of the ongoing and future projects with the ultrafast community at our tabletop. Hope to see you soon!
Avesta’s facilities will be closed for the New Year break from 30 Dec 2017 till 08 Jan 2018. We will resume all operations on 09 Jan 2018. However, we hope to provide periodic e-mail correspondence during the holidays. We wish you a fruitful and prosperous Year 2018!
