PULSED PERIODIC LASER Russian patent published in 2003 - IPC

FIELD: laser engineering; solid state pulsed periodic lasers. SUBSTANCE: laser has light accommodating active element and pump lamp. Upper part of light accommodates pump lamp and lower one, active element, heat-transfer strip transparent for pumping radiation, and hold-down plate. Active element is essentially plate elastically pressed through lower part of light over entire length to heat-transfer strip. Heat-conductivity coefficients λ and λ1, of active element and transparent strip, respectively, heat-transfer coefficients of active-element upper part α1 and of active-element lower part contacting hold-down plate α2 are interrelated by expression λ1≥2λ, 0,5<α2/α1<1. EFFECT: enhanced efficiency of laser cooling. 2 dwg
