Cavity optics consist of Rear Mirror and Front Mirror (also called Output Coupler or Partial Reflector). Rear Mirrors, typically Ge or ZnSe, with very high reflectivity (>99.7%) are key optical components in the laser resonator. 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.
