Abstract
A diffusion reflector is formed of mica ceramics or fluorine plastics containing barium sulfate, on the surface of which gold or silver is vapor deposited to enhance a diffusion reflectance. A reflective cylinder is formed from said diffusion reflector, and laser rods and lamps are arranged in an internal space of the reflective cylinder to form a solid laser device. Thereby, light can be diffused without focussing light within the reflective cylinder, and the laser rods can be uniformly excited.
