POLARITON LASER Russian patent published in 2017 - IPC H01S5/10 

FIELD: physics.

SUBSTANCE: invention relates to laser equipment. Polariton laser consists of filling material (5), resonator (4), which represents two systems of flat, cylindrical rings made from a semiconductor material and inserted into each other with a variable pitch, quantum wells (6) located at the points of the field maximum value. Device also has on both sides of the area of quantum wells and barrier layers (ontop and under bottom) cylindrical rings, each of which is alloyed with a definite concentration, respectively, of p- and n-type (8), (9) and is connected by nanofilament conductors (1) with the resonator rings having on their surfaces metal-coated contacts to feed pumping current (2), (3). Herewith the area of excitation of exciton polaritons represents a circle perimeter, and the area of condensate polaritons, which the laser radiation comes from, is located inside the circle.

EFFECT: technical result is increasing the laser operating temperature up to the room values and higher.
