SOLID-STATE LASER EMITTER WITHOUT FLUID COOLING WITH THERMAL STABILISATION OF DIODE PUMPING Russian patent published in 2016 - IPC H01S3/42 

FIELD: laser engineering.

SUBSTANCE: invention relates to laser engineering. Solid-state laser emitter without fluid cooling and thermal stabilisation of diode pumping has an active element installed in rings, thermal interface and diode pumping unit consisting of a heat spreader surface with projections mounted rigidly on mounting surface, thermoelectric module, which is located between heat spreader and mounting surface, and lines of laser diodes, located on ledges heat spreader surface regularly relative to active element and faced to emitting part. Emitter is equipped with rigidly fixed on mounting surface of resonator in housing of bearing part of which there is an active element. Diode pumping unit is equipped with heater arranged in heat spreader, and bounding box, in which there is a thermoelectric module with an air gap along perimeter. Resonator and diode pumping unit have no contacts.

EFFECT: technical result is enabling increase of efficiency of laser.
