Description
Yellow Ceramic Laser Reflectors
The yellow glaze can cut off wavelengths in the UV range which reduces the amount of heat generated in the laser head. It extends the service life, reduces cooling requirements and operating costs.
The yellow-glazed ceramic concentrating cavity exhibits high reflectivity in the main absorption band of the solid-state laser, and at the same time exhibits the function of reducing the reflectivity in the ineffective absorption band. As a contrast, the diffuse reflective ceramic condenser cavity has high reflectivity in the non-absorptive ultraviolet band of the laser crystal, but it cannot effectively filter out the ultraviolet light that produces a harmful color center to the laser crystal. The highly reflective, UV-absorbing yellow ceramic glaze can obviously improve the shortcomings of ordinary ceramic condenser cavity. It has the characteristics of strong laser radiation resistance, high insulation, corrosion resistance, easy cleaning, and UV absorption.
