TEC Based Temperature Control System:
These units have an integrated high power TEC temperature controller with a full P.I.D. control loop to deliver fast and efficient heat removal from the source laser module. The laser diode is mounted on a Peltier / TEC cooled, nickel plated copper mounting plate. The mounting plate offers very high surface finish and flatness for low thermal impedance. The cooled mounting plate for the laser is attached to a fan cooled air duct to remove the waste heat and keep the laser temperature stable.

QCW and Modulation Functions:
In addition to the standard CW mode, these devices provide external modulation inputs and circuits, as well as an internal function generator for quasi-CW pulse applications. The internal function generator is used to generate QCW pulses from 20 μs to CW. The controller also accepts an external signal from a QCW trigger. Modulation can be TTL or analogue from DC to 50 kHz;
