DEVICE FOR TRANSMISSION OF HIGH-POWER LIGHT RADIATION Russian patent published in 2018 - IPC H01S3/42 G02B6/02 

FIELD: lighting.

SUBSTANCE: device for transmission of high-power light radiation refers to quantum electronics, in particular to technological laser devices. Device for transmitting high-power light radiation comprises of a chamber filled with a coolant, bounded from the end by a transparent optical element, fiber optic bundle with polished end, collected from optical fibers, the end portion of which is installed inside the chamber with the help of, at least two fixing elements, one of which provides a dense packing of the light guides on its clipping portion, there are gaps between the adjacent light guides forming inter-fiber space. Camera is divided into at least two areas communicating through inter-fiber space. First area is bounded by the optical and fixing elements, and the rest are bounded by adjacent fixing elements, first area is provided with a connection for the coolant supply installed on the wall of the chamber, second area is provided with a connection for the coolant pumping installed on the wall of the chamber, In this case, the optical element is a plane-parallel plate of rectangular shape, whose dimensions in height and width exceed the corresponding dimensions of a fiber-optic bundle of rectangular cross-section, located perpendicular to the axis of the fiber optic bundle, while the fiber bundle having a dense packing of the light guides over the entire length of the end portion.

EFFECT: technical result is an increase in the resource of continuous operation of the device in conditions of high transmitted power due to an increase in the cooling efficiency of the end section of the optical fiber bundle and the organization of protection of the pritorz region of the bundle by the coolant flow channel.
