OPTICAL SYSTEM OF SOLID-STATE LASER Russian patent published in 2003 - IPC

FIELD: laser engineering; solid-state lasers. SUBSTANCE: optical system has plurality of laser light sources, optical light-emitting diodes, collimating lens made in the form of planar-convex lens with its surface facing laser light sources, and first optical-resonator mirror. The latter is made in the form of convex-planar lens with its surface facing active element. Lens is disposed between optical resonator mirrors. Second optical-resonator mirror is made in the form of convex-planar lens whose convex surface faces active element. Its concave surface is reflecting one. First mirror has reflecting planar surface. EFFECT: enhanced resistance of laser to vibrations and mechanical thrusts. 2 cl, 1 dwg, 1 tbl
