Low-power laser diodes come in a variety of packages. Most have a monitor photodiode integrated with the laser diode. Generally, laser diodes emit light from both ends of their cavity. By monitoring the rear facet output beam of the laser diode, one can maintain the laser at a constant power level.

Thermoelectric Laser Diode Temperature Controllers are used to control a Thermo-Electric Cooler (TEC) that is typically integrated into a laser diodes package or part of a temperature controlled mounting plate. Laser diode operation is affected by temperature and precision temperature control will help maintain output power, wavelength, and prevent against over temperature conditions that can damage or prematurely age laser diodes.

This technical note presents the experimental results showing the repeatability of power and wavelength measurements using the OMM-6810B Optical Power and Wavelength Meter coupled to an OMH-6722B Silicon Power / Wavehead.
