A Pockels cell driver is a kind of special high-voltage source, nanosecond pulsed electric field (nsPEF) generator, optimized for operation with capacitive-type of loads, designed to produce a fast-switching voltage pulses to control the birefringence of an electro-optical crystal for manipulating the polarization state of light passing through. By this way, one obtains a voltage-controlled wave plate and a possibility to change optical system parameters.

The most of our devices are bipolar when an output pulse voltage U is formed by applying +U/2 to positive output wire and –U/2 to negative. Exception is unipolar QBU‑nano and switches HVSW‑03 and -04 with alternate polarity of pulses (by default, but fixed polarity is possible). The pulse forming circuits of drivers are based on full-bridge topology (MHz rate switches HVSW‑03 and - 04), or a half-bridge concept (other drivers). All given performance values are valid for continuous mode operation, for burst mode (short pulse sequences separated by pauses) they rise sometimes twice.
