In laser technology, a C mount is a method of packaging a laser diode using an alloy of copper and tungsten (CuW, hence "C mount") as a heatsink for the laser component. Typical wavelengths of laser energy generated by C mount devices are between 680 and 980 nm, and with a typical output power rating of up to 7 watts.[1] They are one of three commonly used mounts for laser assemblies, the others being the and the so-called "butterfly" mount.[2]
