Description
Q-switch QBD Pockels cell driver series consists of several boards that differ with output voltage range (up to 6.0kV bipolar) and operating scheme.
QBD-series is specially designed to control Pockels cells by applying a fast switching high voltage. The modules require +24VDC power supply and pulse generator to set an operating frequency. An output voltage level can be programmed in working range by user either manually (through onboard configuration trimpot) or remotely (applying a DC voltage to the respective pin).
There are two possible modifications of output signal type:
- push-up, when a base voltage level equals to zero
- pull-down, when pulses from base bias voltage to ground are generated.
The desired one should be chosen at the time of ordering and could not be changed by user.
QBD-series is based on MOSFET technology and offers high repetition rates and fast transition time for a leading pulse edge. The recovery time by QBD is relatively long (5‑10 μs for the trailing pulse edge vs < 20ns by QBU).
We have also a compact version 4kV QBD-mini Pockels cell driver, an encased laboratory QBD-BT Pockels cell driver, a tiny 3x4cm Q-switch QBD-nano and a QBU Pockels cell driver with variable pulse duration and both fast edges.
