SYSTEM FOR GENERATING AND FOCUSING LASER RADIATION OF EMITTER WITH FIBRE-OPTIC OUTPUT TO REMOTE OBJECT Russian patent published in 2025 - IPC G01S17/88 

FIELD: optics.

SUBSTANCE: invention relates to optical devices and can be used in optical laser beam generators, in the development of laser systems. System for generating and focusing laser radiation of an emitter with a fibre-optic output to a remote object includes an emitter with a fibre-optic output, system for generating radiation and generating radiation of a given beam pattern with an output aperture D and a transmission coefficient T, device for focusing radiation on a remote object; the end face of the core of the fibre-optic output is placed in the effective focal plane of the system. Effective focal distance of the system with an output aperture D is increased in accordance with the ratio: f_in.ef.²K>f_ef.², where: f_in.ef. is increased effective focal distance of the system with transmission coefficient T=K, K is transmission coefficient of system with increased effective focal distance, f_ef. is the effective focal distance of the system with transmission coefficient T=1.

EFFECT: reduced size of radiation spot on remote object, increased density of radiation on remote object.
