The ceramic laser cavity is a type of laser cavity made from alumina ceramic materials. It is an integral part of a laser system, creating and maintaining the lasing action. Ceramic laser reflectors are high-efficiency diffuse reflectors. Near-perfect diffuse reflection and high reflection efficiency are effectively exploited in laser systems where the pump band of the laser host is in the spectral range of 500 nm to 1200 nm. Alumina ceramic materials are preferred for laser cavities due to their high thermal conductivity, excellent mechanical properties, and resistance to thermal shock. Innovacera laser reflectors compared to PTFE polymer reflectors, metal reflectors and packed barium powder diffuse reflectors with several desirable characteristics: Efficient reflection eliminates the need for high-precision focusing reflectors There will be no coating peeling off like specular metal reflectors...
