Ceramic Laser Reflector for Pump Chamber
High purity porous alumina ceramic of 99% Al2O3 content, used extensively for long-life laser reflectors. This material is sintered at high temperatures to achieve a controlled porosity.
Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk refectivity
97% reflectance efficiency at 600-1000nm
Reflectance efficiency exceeds 95% across the wavelength range 400-1200nm (see curve)
Good thermal conductivity
High electrical resistivity
Bulk density (fired), Mg/m3 :3.1
Porosity (apparent), % nominal :22
Flexural strength (ASTM C1161, 3-point), MPa :170
Thermal expansion coefficient
200-500C, 10-6/C 7.9
200-1000C, 10-6/C 9.0
