METHOD OF DETERMINING OPTICAL LOSS IN A SEMICONDUCTOR LASER WITH A RESONATOR OF ARBITRARY SHAPE Russian patent published in 2024 - IPC G01J1/28 H01S5/10 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the study of semiconductor lasers and laser microresonators. Method of determining optical loss in a semiconductor laser with a resonator of arbitrary shape and size includes the formation of several strip lasers with a Fabry–Pérot resonator of different length with cleaved faces from the same epitaxial laser heterostructure as the laser with a resonator of arbitrary shape and size, measurement of the laser generation wavelength in a semiconductor laser with a resonator of arbitrary shape and size, measurement of the laser generation wavelength in strip lasers of various lengths, finding a strip laser, the laser generation wavelength of which coincides with the laser generation wavelength of the laser with a resonator of arbitrary shape and size, determination of optical loss of the found strip laser. Value of optical losses of a laser with a resonator of arbitrary shape and size is characterized by the same value as that of a strip laser.

EFFECT: determination of the value of optical losses in the spectral range of laser generation of a laser with a resonator of arbitrary shape and size.
