QBU-10kV Pockels Cell Drivers
Product details
QBU-10kV is an extension of QBU-series with up to 10kV operating voltage range. Its parameters and distinctive features are:
- Duplicates at its HV output the external driving TTL signal;
- Up to 10kV output voltage;
- Up to 5 kHz @10 kV pulse repetition rate, much higher performance at lower voltages.
- <20 nsec rise- and <25 nsec fall-time

Product Description
QBU-10kV Pockels cell driver
QBU-10kV Pockels cell driver is an extension of QBU-series with up to 10kV operating voltage range. Due to high output voltage it may be used with Pockels Cells working in λ/2 schemes, as well as those operating at longer wavelengths.
Module has fast transition times in both directions, and repeats at its HV output the 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 another user-defined configuration.

Under conditions of appropriate forced air-cooling multi-kilohertz operations are possible even at maximal output voltage.
