Cavity Mirrors
Rear mirrors, known for very high reflectivity (>99.7%), is the crucial optical component in the laser resonator. The 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. Rear mirrors and output couplers are collectively known as laser cavity mirrors.
