Abstract
A microchip laser assembly provides a microchip laser along with an integral Peltier thermoelectric temperature controller and temperature sensor. The temperature sensor measures the temperature of the microchip laser during operation so that the polarity and magnitude of a direct current to Peltier thermoelectric elements may be controlled, thereby controlling the temperature of the microchip laser and stabilizing the optical output frequency or other microchip laser operating parameters. The microchip laser assembly can be mounted, along with a pump source, upon a submount such that the microchip laser can be optically pumped. As a result of the construction of the microchip laser assembly, the temperature of the microchip laser can be controlled independent of the temperature of the pump source.
