Variable Duty Cycle Femtosecond Pulse Picker Pismo OG8/25-2
Pismo OG8/25-2 has one Pockels cell based on DKDP crystal and two independent high voltage shutters. Each of HV shutters generates bell-shaped HV pulse with amplitude in the range 6-9 kV (halfwave voltage for DKDP is ~8 kV at 800 nm) and duration ~10 ns at level 10% of maximum amplitude. Maximum repetition rate of each HV shutter is 25 kHz (adjustable from 0 to 25 kHz). The delay between HV pulses can be varied in the range from 10 ns to 100 microseconds (or more, if required).
