POWERFUL SEMICONDUCTOR LASER WITH NONLINEAR MICROCHANNEL COOLING SYSTEM Russian patent published in 2010 - IPC H01S5/24 

FIELD: physics.

SUBSTANCE: invention can be used in optoelectronics for research, design and manufacture of powerful semiconductor lasers, laser semiconductor matrices and laser systems based on said matrices. The powerful semiconductor laser matrix consists of semiconductor crystals (lines of laser diodes), microlenses, insulating pads, electrodes and a cooler or system of coolers, in the top contact plane of which there is a system of microchannels carrying cooling liquid. The microchannels in the top contact plane of the coolers on the entire length of the crystals Lx have a variable cross-section, which varies in accordance with a nonlinear temperature profile ΔT(Lx)I_A of the crystals, during operation of the laser in continuous mode with variable step and in form of triangles whose vertices face the laser diodes.

EFFECT: improved quality of laser radiation due to attainment of the same temperature on the plane of the crystal housing on the entire length of the crystals working in continuous mode.
