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.
