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. In 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 ceramic glaze can obviously improve the shortcomings of ordinary ceramic condenser cavities. It has the characteristics of strong laser radiation resistance, high insulation, corrosion resistance, easy cleaning, and UV absorption.
