LASER GUN OF SOLID-STATE LASER WITH DIODE PUMPING Russian patent published in 2017 - IPC H01S3/42 

FIELD: laser engineering.

SUBSTANCE: invention relates to laser equipment. Laser gun has an active element in the form of a rod, optical pumping sources located on holders around the active element, a system of cooling the active element and the optical pumping sources, flanges and an element connecting the flanges. Holders are located in coaxial holes of the flanges. Cooling system comprises a tube encircling the active element to form a radial clearance, an input, an outlet collectors and channels of the holders. Element connecting the flanges represents a frame containing parallel plates connected with ribs. Holders have on both sides limiters interacting with end surfaces of the flanges. One of the limiters of each holder is made with flats interacting with slots of the flange.

EFFECT: technical result is enabling higher cooling efficiency.
