LASER EMITTER Russian patent published in 2025 - IPC H01S5/24 

FIELD: quantum electronic equipment.

SUBSTANCE: invention relates to quantum electronic engineering and specifically to designing power semiconductor injection devices, laser emitters, diode pumping and articles based thereon. Laser emitter, according to the solution, has a heat-removing plate made of a ceramic composite material of the following composition: diamond 50-75 vol.%, silicon carbide 15-35 vol.%, silicon – balance vol.%, having on all sides a multilayer coating formed from an adhesive intermediate layer and a metal coating with high electroconductivity, on the upper surface of which, on one long side, a crystal of the heteroepitaxial plate is placed, and on the other long side – an electrically insulating plate, wherein the crystal and the electrically insulating plate are not in contact with each other, and a high-conductivity metal plate installed on the electrically insulating plate and the crystal, forming an ohmic contact, wherein all plates have openings for mounting and coolant flow.

EFFECT: reduced heat resistance in the design of the laser emitter due to use of materials with high heat and temperature conductivity.
