STA-PCD-1 - Pockels Cell Driver
Pockels Cell Driver
Zoom in
Printable version
View drawings
High-voltage pulse is formed by a symmetrical, bipolar output in «Switch-On» operational mode
Single supply voltage range +5 V to +7.5 V
Built-in, pulsed HV-Source
Adjustment of a high-voltage pulse either directly on the board (through built-in potentiometer) or remotely
Significantly reduced electro-magnetic noise
Positive logical trigger 3 ÷ 8 V
Highly reliable topology
Ultra-compact size – designed for handheld Q-switched laser heads

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
1a max. output voltage amplitude could be achieved while driver is supplied with +7.5 V 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.
