99% Alumina Laser pumping cavity ceramic reflector
The material of the ceramic reflector is 99% Al2O3 . Its green body is fired at a suitable temperature to retain the proper porosity and strength. The surface of the ceramic reflector is coated with a high-reflectivity ceramic glaze, so it has a longer service life and a more diffuse reflection compared to the gold-plated reflector. Production Process Preparation of the green body Preparation of glaze slurry: raw material weighing, grinding, sand screening Glazing: glazing by spraying Glaze burning: The glazed product is burning at a high temperature Inspection: Appearance inspection, dimensional measurement, and reflectance measurement Packaging Prime Features Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity 97% reflectance efficiency at 600-1000nm Reflectance efficiency exceeds 95% across the wavelength range 400-1200nm (see curve) Controlled porosity Good thermal conductivity High electrical resistivity Precautions for the u...
