Optical Mirrors - CO2 Mirrors

CO2 Mirrors

Reflective CO2 mirrors must have low reflection losses, high optical quality, and good resistance against extreme optical intensity. CO2 laser cavity optics consist of a rear mirror and a front mirror (also called an output coupler or partial reflector ). Rear mirrors, typically ZnSe, with very high reflectivity (>99.7%) are key optical components in laser resonators. Output couplers are partially reflective mirrors to extract a portion of the laser beam from the laser resonator. They often require a slight wedge to prevent interference from multiple reflections inside the component.
