High-power double-clad optical fiber cladding light stripper device and manufacturing method

The invention provides a high-power double-clad optical fiber cladding light stripper device and a manufacturing method. The light stripper device comprises double-clad optical fibers (116), an optical module (111), a fixing material (113) and water-cooled tubes (117 and 118). The double-clad optical fibers (116) penetrate through the optical module (111) and the fixing material (113). The optical module (111) is arranged in the fixing material (113). The water-cooled tube (117) is installed on the lower portion of the fixing material (113). The optical module (111) is of a three-layer waveguide structure. A heat dissipating material is adopted as the fixing material (113). According to the device, double-clad optical fiber inner cladding is corroded to form an opposite conical structure, and placed into the waveguide structure manufactured with semi-hollow cylinders and semi-solid cylinders made of a transparent material so as to leak light, the light leaked by the inner cladding is leaked uniformly in the length direction of the optical fibers, power density of the light and heat is reduced, and the situation that because light leakage is excessively concentrated, optical gel is burned out can be avoided.
