QBU-BT-10kV-series Pockels Cell Drivers

The modules are encased version of QBU-10kV boards, more functional than QBD drivers and may be used for advanced beam control: advanced q-switching, beam slicing, pulse picking. The model is a high voltage extension of QBU-series

QBU-BT-10kV high voltage Pockels cell driver 2

Universal driver, suitable for advanced q-switching, beam slicing, pulse picking.

  • Internal or external synchronization
  • Triggering by an arbitrary external TTL signal output provides various operating schemes
  • Up to 10 kV output voltage
  • Over 5 kHz repetition rate at maximum voltage, over 50 kHz at lower voltages
  • < 20 ns / 25 ns rise/fall time

QBU-BT-10kV-series is specially designed to control Pockels cells by applying a fast switching high voltage. The module is an extension of QBU-BT-series operating voltage range up to 10 kV (bipolar). The voltage level, operating frequency and pulse width can be selected in working range by user through RS232 or through the front panel. Triggering is carried out automatically or via a signal from an external device.

Devices are encased and easy for the user to mount, they run on common 100-240 V AC 50/60 Hz, so, you don't need extra power supply for the driver.

Different operating modes by output signal form are possible:
• push-up (= normally off scheme), when a base voltage level equals to zero, triggering is internal
• pull-down (= normally on scheme), when pulses are generated from base bias voltage to ground, triggering is internal
• user-defined scheme, with arbitrary width and frequency of pulses, triggering by an external low voltage arbitrary TTL signal, external synchronization mode

QBU-BT-10kV-series is based on MOSFET technology and offers high repetition rates and fast transition time for both pulse edges
(< 20 ns rise time / < 25 ns fall time). Due to high efficiency and embedded forced air cooling multi-kilohertz operations are possible even at maximum output voltage.
