PCM-7140 Series

PCM-7140 Series


The PCM-7140 Series provides a compact pulsed and QCW current source designed to drive laser diodes, bars, arrays, or any low impedance load.

The output current may be set with an internal potentiometer or an external analog voltage. The pulse width is controlled with an external trigger source.

The system requires two DC supplies for operation: 12 V for housekeeping and a voltage ≤ 20 V above the laser diode’s forward voltage.

The laser or load is connected to the PCM-7140 with a 100 cm length of 18 AWG twisted pair cable (included). This same cable has the DC input connection from the high voltage power supply.

The PCM-7140 module is liquid cooled with a liquid temperature of 11 °C to 22 °C with a flow rate of 6 liters per minute. The connection type is 3/8” tubing.
