Abstract
A temperature controller module for electronically controlling the temperature of a device, such as a pump laser or laser diode, controls the device temperature based on low heat dissipation inductors and current sources. The temperature controller module shuts off the thermoelectric cooler when the temperature of the laser exceeds a predetermined amount. Further, the temperature controller module is integrated in a compact, self-contained modular form to allow use in space critical applications.
