Ceramic reflector
Ceramic reflectors are recently used in laser pump chambers
The ceramic reflector is used 99% Al2O3 content which is sintered at the proper temperatures to achieve a controlled porosity and strength. The surface of the reflector is coated with high reflectivity ceramic glaze, compared with gold-plated reflector, the biggest advantage is its extremely long life time, diffuse reflection characteristics.
Prime features:
1. Full surface of the glaze to maximize reflectivity and easy cleaning
2. 97% reflectance efficiency at the wavelength of 600-1000nm
3. Reflectivity exceeds 95% across the spectrum range 400-1200nm
4. Controlled porosity and high strength
Physical properties:
Color: white
Density: 3.1g/cm3³
Porosity: 22%
Flexural strength: 170MPa
Thermal expansion coefficient: 7.9×10-6¬¬/С（200～500℃）
9×10-6/С（200～1000℃）
