LASER WITH ADJUSTMENT DEVICES Russian patent published in 2021 - IPC H01S3/08 H01S3/86 H01S3/10 

FIELD: quantum electronics; laser technology.

SUBSTANCE: invention relates to the field of quantum electronics and laser technology, in particular to solid-state fiber lasers, and can be applied in nonlinear optics, analytical spectroscopy, optical instrumentation, medicine, ecology, photodynamic therapy. Disclosed is a laser with a pump source, alignment devices, a resonator with an active element having a fiber effect and installed by means of a mounting unit so that it can rotate relative to the optical axis of the laser source, between optically coupled first and second resonator mirrors, placed by means of corresponding holders with adjustment devices of the first and of the second resonator mirrors on the end flanges of the resonator, a platform with the third adjusting device for moving the resonator along the height and normal to the optical axis of the laser source and a device for converging and converting the radiation of the laser source, placed between the laser source and the resonator with the ability to move the converting and converting device along the optical axis laser by means of the fourth adjusting device and optically coupled with the active element.

EFFECT: fiber laser can reduce the distance between the resonator mirrors (7, 8) with very precise adjustment of the position of the active element (4) and resonator mirrors (7, 8) relative to each other and the optical axis (6) of the laser pump source (1) by at least 50% due to independent fine adjustment of the position of each of the resonator mirrors (7, 8), the device for converging and converting (15) radiation from the laser pumping source (1) and the active element (4).
