Abstract
A system, method, and device for efficiently maintaining a stable operational temperature for precise operation of a laser. The system can include an ambient temperature sensor, a cooler controller adapted to control a cooler having an adjustable setpoint, a processor, and a memory coupled to the processor. The memory can store software instructions that, when executed by the processor, cause the processor to perform operations that can include receiving data from the sensor and determining the ambient temperature based on the received data. The determined ambient temperature can be compared to a current setpoint. When the delta exceeds a predetermined threshold, the setpoint can be adjusted to enable the operating environment of the laser to reach a control temperature closer to ambient conditions (and within a predetermined operating temperature range of the laser). Adjusted setpoint data can be transmitted to the cooler controller to adjust the setpoint of the cooler.
