QBU-mini-series consist of several Pockels cell drivers differ with their output voltage range (see also How to order? section) and covering range up to 3.5 kV.
Modules have fast transition times in both directions and repeat at their output external driving TTL signal. As a result they may be used for q-switched lasers of push-up scheme, pull-down scheme as well for mixed-type or other user-defined scheme.
Under conditions of appropriate forced air cooling, low load capacitance and low operating voltage modules may achive performance up to 30 kHz (CW) or 50 kHz (in burst-mode).
