Ceramic Reflector Information:

Diffusive ceramic reflectors for Nd:YAG laserCeramic reflector typical application is pumping chambers for Nd:YAG lasers — low to high power, single or multiple lamp designs. Pumping chamber reflectors of this material are virtually indestructible, and prove a highly cost effective alternative to metal coated types. A porous alumina ceramic of 99.7% Al2O3 content, used extensively for long-life laser reflectors. This material is sintered at high temperatures to achieve a controlled porosity. Ceramic reflectors also can use many other kinds of lasers, such as for Diode-pumped Solid-state Lasers.

Ceramic Reflector features:

Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power. Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity

1. Resists chemical attack

2. Controlled porosity

3. Has high strength

4. Protótipos feitos de Cerâmica de Alumina de Alto Desempenho em qualidade serial

5. ″* 4″

6. the surface of the glaze to obtain the maximum reflectivity and easy to clean

7. the wavelength of 600-1000nm at the reflectivity of 98%

8. in the 400-1200nm spectral range of reflectivity of more than 96%

9. the body has the appropriate porous and high strength characteristics

Ceramic cavity reflectors work particularly well in Ruby and Nd:YAG laser pumping chambers and can be a highly cost effective alternative to metal coated reflectors. They are also used extensively as reflectors in housings for high intensity lamps.
