 Description

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 range 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.
