Pockels cell driver boards

Driver for Q-switching pulse shape

Drivers for Q-switching are relatively simple, allow to change output voltage level and pulse repetition rate. They provide pulses with fast leading edge (< 20 ns) and relatively slow (some μs) trailing edge.

QBD-series, up to 6 kV.
QBD-mini, compact version of QBD, up to 4 kV

QBD-nano driver for Q-switching pulse shape QBD-nano avalanche transistor driver, super fast (1-3 ns rise), tiny (40x30x8 mm), fixed pulse duration (about 0.7 μs)

QBY-4050 10 W low power consumption driver for Q-switching, pulse slicing, battery powered equipment, some LIDAR systems

Driver for Pockels cell pulse shape

Drivers for advanced Q-switching are more improved, allow to change output voltage level and advanced switching control to vary pulse repetition rate and width (long pulses, from 200 ns to CW). They provide pulses with both fast edges (< 15-20 ns) and alow to switch high voltage on the cryslal shortly before pull-down pulse to prolongate the crystal life-time.

QBU-series, up to 6 kV.
QBU-mini, compact version of QBU, up to 4 kV
QBU-mini-SP, compact version of QBU with short pulses, up to 4 kV

QBU-10kV-series, up to 10 kV.

Driver for Pockels cell pulse shape

More advanced drivers for pulse picking and pulse slicing allow to change output voltage level, pulse repetition rate and pulse duration (short pulses, from ~15 ns to 2000 ns). They provide pulses with both fast edges (< 7 ns).
