Problems solved by technology

However, traditional corrosion-type high-power cladding optical strippers generally only include one cladding optical stripping area, which bears a large amount of heat, resulting in a rapid temperature rise, which is easy to burn out, which is not conducive to realizing high-power laser output

Abstract

The invention discloses a cascade cladding light stripper and a manufacturing method thereof. The cladding light stripper comprises a first optical fiber, a second optical fiber, a quartz tube and a metal shell. According to the invention, cladding light is stripped layer by layer step by step through a plurality of cascaded cladding light stripping devices and a segmented corrosion method to guide away heat generated by the cladding light or the cladding light step by step and stage by stage, so that high-power cladding light stripping can be realized, local high temperature is effectively avoided, the cladding light stripper can be applied to a high-power optical fiber laser, and manufacturing difficulty is low.

Description

technical field [0001] The invention relates to the field of lasers, in particular to a cascaded cladding optical stripper and a manufacturing method thereof. Background technique [0002] In high-power all-fiber lasers, the cladding structure of double-clad fibers inevitably contains residual pump light, amplified spontaneous emission, and signal light leaked due to factors such as non-ideal splicing and fiber bending, which will deteriorate the cladding light. The beam quality of the output laser may even damage the semiconductor pumping source and other fiber optic devices in the laser system, thus seriously affecting the stability of the laser. Therefore, how to reliably and efficiently strip the cladding light from the cladding waveguide is one of the key issues in the development of high-power all-fiber lasers. [0003] The cladding light stripper (CLS) is a passive device used to filter the cladding light in the optical fiber. Its basic working principle is to refrac...
