Q-switch drivers 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 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

Advanced Q-switch drivers 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 allow 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.

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

  • ultra fast (1-3 ns rise), ultra small (40×30 mm) kHz-range QBD-nano for cavity dumping
  • ultra fast (1-3 ns rise and fall), small (80×50 mm), kHz-range, 0-800 ns duration QBU-nano for regenerative amplifier control.
  • ultra fast (3-4 ns rise and fall), small (80×50 mm), up to 10 kHz-range, 10-1000 ns duration QBY-4001 and QBY-4010 on GaN transistors, for regenerative amplifier control.
  • ultra fast (3-4 ns rise and fall), up to 5 kHz-range, 10-1000 ns duration encased driver for laboratory QBY-BT on GaN transistors, for regenerative amplifier control and pulse picking.
