QBD-series is a line of quite simple, compact and inexpensive Pockels Cell Drivers.
Features:
QBD is a series of high repetition rate Pockels cell drivers allowing simple and reliable control of Q-switched lasers. Output voltages may be selected in the range of up to 6 kV.
Driver may be manufactured in two modification: for pull-down scheme (= normally on scheme), and for push-up scheme (= normally off scheme):
High repetition rates and fast transition times are additional benefits.
