Pockels cell driver STA-PCD-1 has been designed for cavity dumping and Q-switching of solid-state lasers equipped with electrooptical Q-switches based on BBO or DKDP crystals. The modified version STA-PCD-2 provides unipolar output and may be used with Q-switches and modulators based on RTP, KTP, LITA, LNB crystals.
The device could also be used as a generator of nanosecond electrical pulses.

1 is set from the built-in potentiometer or remotely, upon request the voltage output level can be adjusted to any value by means of capacitive voltage divider.
1a max. output voltage amplitude could be achieved while driver is supplied with +7.5V voltage
2 depends on the load inductance and output voltage amplitude.
3 is set by manufacturer.
4 Delay depends on the trigger pulse. The higher trigger amplitude the shorter delay.
