Systems and methods are described herein to thermally regulate laser diodes. During operation, the structure of a laser diode may generate heat, which will affect the stability and accuracy of the output wavelength of the laser diode. During an OFF stage, the structure of the laser diode will then lose heat, creating a thermal gradient as the laser diode is switched between operation and an OFF state. The systems and methods provide constant average heat and a stable thermal gradient by integrating a laser diode power-coupled supply and a heater onto a heatspreader, such that the output wavelength of a coupled laser diode may be stabilized.

Heater-on-heatspreader

Systems and methods are disclosed herein for controlling laser beams for a plurality of collocated laser assemblies. The laser beams are optimized by controlling outputs of a primary power source (current for generating a laser beam) and a secondary power source (heating device) for each of the respective laser assemblies. The states of the power supply may be cycled and modulated to provide optimal performance.
