After amplification, the picosecond pulses are temporally
compressed to 50 - 100 fs pulses (depending on the input pulse
duration) by one-grating pulse compressor. At the pumping with
a frequency doubled Nd: YLF pumping laser (1000 Hz, 20 mJ/
pulse), the compressor gives 1.0 mJ pulses at 800 ± 20 nm.
Wedge 50 femtosecond amplifier system comprises:
1) Optical unit of two-mirror confocal multipass amplifier with
installed inside stretcher, pulse picker with HV Pockels cell
driver, and pulse compressor.
2) Synchronization electronics unit.
