SMALL-SIZE LASER HEAD WITH LIQUID COOLING Russian patent published in 2017 - IPC H01S3/42 

FIELD: physics.

SUBSTANCE: small-sized liquid-cooled laser head contains an active element in the form of a rod and a reflector, an optical pumping source, a cylindrical lens, a plate of material transparent for radiation, fixed by a frame on the case opposite the source of optical pumping, and channels in the housing. At the same time, the active element is fixed with clamps in the body, the reflector is fixed to the bottom of the body cavity, to which the holder is attached and installed through the adjusting plate. There is an optical pumping source on the holder, which uses a matrix of laser diodes, on the radiating part of which there is a cylindrical lens located along the active element. The holder is provided with an inlet and outlet nozzles with channels connected to the channels of the holder which are connected to the channels of the adjustment plate connected to the channels of the housing which are connected to the housing cavity. Adjusting elements are installed between the frame and the body.

EFFECT: ensuring the possibility of increasing the efficiency of pumping and cooling the laser head.
