SOLID-STATE LASER EMITTER Russian patent published in 1998 - IPC

FIELD: laser engineering. SUBSTANCE: solid-state laser emitter has pump incorporating reflector shaped as round cylinder, optical pumping source, and two active elements; axes of optical pumping source and active elements are parallel to cylinder axis. Active elements and optical pumping source are installed in pump so that axes of active elements and optical pumping source are equally spaced from reflector center and axes of active elements are equally spaced from optical pumping source axis; distance between axes of active elements is chosen from expression 4Ra²/(R²+a²), where R is reflector radius; a is distance between optical pumping source axis and reflector center; permissible deviation of axes of active elements from mentioned position is not greater than r, where r is active element radius. EFFECT: improved design. 2 dwg
