Description
QBY-BT Pockels cell driver is an encased version of QBY-4001, a Pockels cell driver by OEM Tech based on GaN transistors. It provides bipolar voltage pulses (3-4 ns rise/fall) on the outputs to control the birefringence of an electro-optical crystal to change the polarization state of light passing through. It is a compact bench-top model with fast switch to obtain short pulses starting from 10 ns. The QBY-BT is equipped with internal controller to manage the output and with cooling fan, which made it possible to increase the max. rep. rate in five times at the maximal voltage in comparison with QBY-4001.
One can adjust pulse amplitude, pulse repetition rate and width manually or by external controlling device through RS-485 interface. Pulse controlling TTL signals J1 and J2 are generated internally under controller regulation. Simultaneously, the module generates an output synchronization signal (TRIGGER OUT) with a definite time shift towards to J1, this could help to synchronize the whole system. It is also possible to connect an external pulse generator to set an operating frequency and pulse width.
Output voltage is up to 4 kV, max. rep. rate strongly depends on selected output voltage value and on load capacitance. We recommend therefore to use the shortest possible cables and choose a Pockels cell with lower capacitance.

Frequently Asked Questions
The QBY-BT series Pockels cell driver is used for controlling regenerative amplifiers, offering a wide range of output voltages and fast rise and fall times.
The QBY-BT driver can provide a wide range of output voltages from 0 to 4kV.
The pulse width is smoothly adjustable in the range of 10 to 1000ns with sub-nanosecond steps.
The delivery includes the QBY-BT Pockels cell driver, an AC/DC power supply, and a 15cm long HV output cable.
Users should read the entire user manual carefully, as the equipment may be dangerous. Only use a symmetrical (differential) high voltage probe for measurement to avoid driver failure.
The QBY-BT driver supports both external synchronization mode with extra low delay/jitter and a fully functional internal synchronization mode.
The QBY-BT driver has fast rise and fall times of 3-4ns.
