LASER WITH CONTROLLED-HEATING-TEMPERATURE ACTIVE ELEMENT Russian patent published in 1997 - IPC

Abstract RU 2091934 C1

FIELD: quantum electronics; solid-state lasers. SUBSTANCE: laser has solid-state cylindrical active element 3 with internal cylindrical channel 4, pump lamp 2, open optical cavity 1. Temperature sensor is placed in channel 4 and has two light-conducting fibers 5 coming in contact at room temperature. Superconducting fibers are interconnected by metal tube 6. One of fibers has light-isolating sheath and is connected to photodetector 8 coupled with indicator 9. Metal tube 6 is covered with light-absorbing or blackening coat. EFFECT: improved design. 1 dwg
