Abstract
In a high-efficiency solid-state laser device with an optical resonator including a solid-state laser medium in the form of a slab crystal, for example, a flash lamp serves as the excitation light source of the solid-state laser medium, and a reflector serves for injecting light produced by the light source into the laser medium. A reflector made of a foamed quartz glass has high diffusion reflectance over a wide range of wavelengths from the infrared to the ultraviolet. Foamed quartz glass is preferred also as an integrating sphere material for optical measurement.
Claims4
A solid-state laser device comprising:
- a solid-state laser medium;
- a light source for exciting said solid-state laser medium;
- and
- means for injecting light produced by said light source into said solid-state laser medium, said injecting means comprising a glass reflector having a plurality of small bubbles therein.
A solid-state laser device comprising:
- a solid-state laser medium;
- a light source for exciting said solid-state laser medium;
- and
- means for injecting light produced by said light source into said solid-state laser medium, wherein said injecting means is a diffusion reflector having a front surface and a back surface, said front surface facing the light source such that said reflector diffusely reflects said light produced by said light source, and said back surface having a highly reflective material adhered thereto.
