Abstract

The invention is a high-power laser coupling optical fiber head structure, including: a main body, divided into big- and small- diameter ends, where there is a screw thread in the end part of the small-diameter end, there is a central through hole to hold the optical fiber in the middle of the small-diameter end, there are two through holes made on two sides of the central through hole, and the two though holes are the cooling water channel, there are two water holes made on the big-diameter end, and the two water holes are connected with the two through holes, respectively; a front stopper and a back stopper, having the same structure; there is a through hole in the centre of the front stopper, there are two grooves corresponding to the two through holes on the main body on two sides of the through hole, the front and back stoppers are welded on two ends of the main body, respectively, the two grooves are connected with the two through holes; an optical fiber head fixing ring, there is a circular hole in the fixing ring and the fixing ring is covered on the small-diameter end; two water mouths are welded on the two holes.

Description

technical field [0001] The invention provides an optical fiber head structure and an optical fiber head cooling method, in particular to an optical fiber head structure and an optical fiber head cooling method for high-power laser coupling. Background technique [0002] In medical treatment, pumping, material processing and processing, etc., a large laser fiber-coupled output power is required. When this high-power laser is output through an optical fiber, it is sometimes output by a single optical fiber. Sometimes in order to increase the fiber-coupled output power, it is necessary to Fiber-optic coupling output of high-power laser line array is realized by fiber bundle array. In high-power laser fiber coupling, whether it is a single fiber output or multiple fiber output, the most widely used methods for fixing a single fiber and fiber head, between multiple fibers, and between multiple fibers and fiber heads are Use optical glue (usually 353ND) to glue single or multiple...
