Claim 0:
1. A system for detecting a laser beam, the system comprising:
a controller comprising a processor and a memory;
a thermoelectric cooler comprising a hot side and a cold side, the thermoelectric cooler operable to receive a series of electrical signals from the controller;
a heat spreader comprising a first surface and a second surface, the heat spreader in thermal communication with the thermoelectric cooler; and
a temperature-sensitive structure characterized by an operating temperature band and in thermal communication with the heat spreader, wherein the temperature-sensitive structure is configured to receive the laser beam, and wherein:
a region of local heating is produced on the temperature-sensitive structure in response to receiving the laser beam; and
the memory stores instructions that, when executed by the processor, cause the controller to:
generate the series of electrical signals;
cause the thermoelectric cooler to transfer heat from the cold side to the hot side; and
maintain temperatures of the region within the operating temperature band.
