Description
Range of drivers for Pockels cells are fast HV switches designed to load and unload capacitance of Pockels cell with several nanosecond edges.
Amplitude of output pulses to Pockels cell is about equal to HV supply voltage. Only exception is DP-FAM series drivers that allow to control the amplitude of each pulse by analog voltage input.
Design adaptation for particular OEM customer is possible and can include optimizing of mechanical design, output switch for voltage, repetition rate, rise/fall time and pulse duration lengthening etc.
Almost all the drivers can work in up to 5 MHz bursts. Range of DC/DC type HV power supplies is manufactured to provide a complete Pockels driving solution.
