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
