PCM-7700 200A Laser Diode Driver

PCM-7700 200A Laser Diode Driver


The PCM-7700 is an air-cooled, high-power current source designed to drive laser diodes, bars, and arrays. The output current can be set from 5 A to 200 A. The load voltage for the PCM-7700-48 is 0 V to 30 V, and for the PCM-7700-EX is 0 V to 35 V. The pulse width is adjustable from 500 µs to 50 ms with a pulse repetition rate from single shot to 1 kHz.

The PCM-7700 output current may be set with the potentiometer on an included evaluation board or an analog voltage. The pulse width is controlled with the trigger input.

The instrument supports analog and digital control modes. In digital mode, a DC voltage sets the output current and the trigger inputs sets the pulse width. In analog mode, the output current follows an analog signal.

For automated applications, complete control of the instrument is provided through a DB15 male connector.


  • Output Current up to 200 Amps
  • Output Voltage up to 30 Volts (35 Volts for the PCM-7700-EX model
  • Output Power up to 1250 Watts
  • Digital and analog control modes
  • DB-15 remote interface for automated operation


The PCM-7700 is designed to drive laser diodes, bars and arrays with forward voltages up to 30V (35V or the PCM-7700-EX model).
