Reflective laser optics mirrors must have low reflection losses, high optical quality, and good resistance against extreme optical intensity. CO2 Mirrors Reflective laser optics mirrors must have low reflection losses, high optical quality, and good resistance against extreme optical intensity. Cavity Optics 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.
