FIBRE LASER SYSTEM WITH MULTIPLE BEAMS Russian patent published in 2019 - IPC B23K26/00 H01S3/67 

FIELD: optics.

SUBSTANCE: group of inventions relates to the technology of inputting light coming from a plurality of fibre laser devices into one optical component and controlling radiation coming from said laser devices. Fibre laser system with multiple beams of output radiation for creation of several beams of output radiation of fibre laser. System comprises multiple modules of fibre laser system, multiple output fibres and volumetric optical element. Modules of fibre laser system create multiple separate bundles of output radiation of fibre laser. Corresponding bundles of output radiation differ by one or more beam characteristics. Each of the output fibres is configured to deliver one of said individual bundles of output radiation of the fibre laser. Each of said output fibres is connected to volumetric optical element. Optical element is configured to receive separate bundles of output radiation of fibre laser from output fibres and output separate beams of output radiation of fibre laser substantially at distance from each other.

EFFECT: technical result consists in creating a laser system using an optical element, which can output incoherent laser beams in a given configuration, in which parameters of the output radiation can be controlled.
