AI Technical Summary

Problems solved by technology

Working at high temperature for a long time will lead to accelerated breakage of chemical bonds inside the high-fold adhesive layer, shortening its life and accelerating its aging
Since the optical fiber is wrapped in high-refraction glue, the change of high-refraction glue will affect the stability of the laser output signal light, thereby affecting the life of the entire laser

Abstract

The invention relates to the technical field of optical fiber laser devices, in particular to an optical fiber cladding light stripper and an optical fiber processing system. A fixing base of the optical fiber cladding light stripper is used to fix an optical fiber. A heat dissipation device includes a cover and a multi-layer heat absorbing structure. The cover covers and is buckled downward ontothe fixing base. A heat absorbing channel is formed on the inner side of the cover along the axis of the fixing base, so that the optical fiber is located in the heat absorbing channel. The multi-layer heat absorbing structure is arranged inside the side wall of the cover, and is used to absorb the energy of reflection and / or refraction of optical fiber cladding light. In the optical fiber processing system, the optical fiber cladding light stripper is fixed on a disposal platform and is connected with an optical fiber disposal device. The stripper and the processing system can prevent excessive cladding light from passing through high-refractive-index gel during stripping of optical fiber cladding light, so as to improve the output stability of signal light and prolong the service life ofoptical fibers.

Description

technical field [0001] The invention relates to the technical field of optical fiber laser devices, in particular to an optical fiber cladding optical stripper and an optical fiber processing system. Background technique [0002] Cladding pumping technology is one of the key technologies for fiber lasers to output high-power lasers, but the cladding structure of double-clad fibers will inevitably contain residual pumping light, amplified spontaneous emission, and signals leaked due to fiber bending and other reasons Light. If the cladding light is directly output, the beam quality of the output laser will be deteriorated, and it may even damage other fiber optic components, thereby affecting the stability of the fiber laser. Therefore, efficient and reliable stripping of cladding light is of great significance for the development of high-power all-fiber lasers. [0003] The optical fiber cladding light stripper is a passive device that can filter out the cladding light of ...
