TO-Can Laser Diode Heat Dissipation

The heatsink must be capable of dissipating the waste heat generated by the laser. Lower power devices may only need to be mounted to a baseplate. However, higher power devices require a more substantial heatsink or a forced air, finned heatsink, and laser diodes arrays (bars) may need active cooling to handle the waste heat.
