High voltage modulator for electrooptical crystal
Function
Provedes forming of control signal for electrooptical crystal in laser resonator Q-switch. Signal parameters operating modes are controlled from PC with USB interface. Control software operates in OS Windows XP/Vista/7.
Design variants
- embedded module;
- stand-alone module with air cooling and HV-connector for electrooptical crystal plug-in
