Ceramic Laser Reflector for Pump Chamber
High purity porous alumina ceramic of 99% Al2O3 content, used extensively for long-life Ceramic Laser Reflector . This material is sintered at high temperatures to achieve a controlled porosity. 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 Physical properties Color: White Bulk density (fired): 3.1 g/cm 3 Porosity (apparent), nominal: 22% Flexural strength (ASTM C1161, 3-point): 170 MPa Thermal expansion coefficient: 200-500℃, 7.9*10 -6 /C 200-1000℃, 9.0*10 -6 /C Typical Applications Pumping chambers for flash lamp and continuous-wave lasers using media such as Nd:YAG lasers, Alexandrite — low to high power, single or multiple lamp designs used for welding, cutting, marking, and in medical lasers.
