used in Pismo OG8-100-1 pulse picker
Pulse pickers
The pulse picker consists of the pockels cell, high voltage driver, synchronization and delay generator. It is suitable for single pulse selection from train of femtosecond or picosecond pulses. Also the device is used for pulse slicing in order to increase contrast.
