Abstract

The invention provides a fiber cladding residual light all-wave detachment method and a fiber cladding residual light all-wave detachment device, which are applied to the technical field of photoelectrons. The detachment method comprises steps: 1) a section of outer cladding (4) is peeled on the fiber, and an inner cladding (3) is exposed as a leakage section (5); 2) a quartz tube (6) is fused on the inner cladding (3); 3) a corrosive agent is adopted to corroding the quartz tube (6), surface roughening is carried out on the quartz tube (6), and residual light in the inner cladding (3) is emitted uniformly via the roughened surface of the quartz tube (6); and 4) water-cooled packaging is carried out on an optical module formed by a fiber core (1), the inner cladding (3) and the quartz tube (6), making of a detachment device is completed, and the cladding light is thus detached. According to the fiber cladding residual light all-wave detachment method and the detachment device, the residual light in the fiber cladding can be conveniently and quickly detached, the fiber is not damaged, and the residual light detachment efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of optoelectronics, and more specifically, relates to a method for all-glass stripping of optical fiber cladding residual light. The present invention also relates to a method of applying the optical fiber cladding residual light all-glass stripping method to complete the cladding of an optical fiber. Residual light stripped optical fiber cladding residual light all glass stripped device. Background technique [0002] Fiber lasers are widely used in various industries due to their advantages of high power, high beam quality and high reliability. In the prior art, residual light inevitably exists in the cladding of the optical fiber at the end of the fiber laser because the pumping light is not completely absorbed or the core signal light leaks into the cladding. If this part of the residual light cannot be effectively stripped, the subsequent optical devices will be seriously damaged, while the beam quality...

AI Technical Summary

Problems solved by technology

If this part of the residual light cannot be effectively stripped, it will seriously damage the subsequent optical devices, while reducing the beam quality and greatly reducing the life of the fiber laser

At present, a widely used optical fiber cladding residual light all-glass stripping method is to peel off the outer cladding and coating layer of the optical fiber, and apply high refractive index glue. The disadvantage of this method is that the temperature distribution on this section of optical fiber is not uniform, and there are local Problems such as high temperature; another improved method is to coat different refractive index glues (from low to high) in sections along the stripping direction. The uniformity of temperature distribution on the optical fiber using this method is improved, but the polymer refractive index glue There are problems such as light absorption and heat absorption, while the refractive index glue blocks the effective transfer of heat to the heat sink and the surrounding environment

In addition, the above two methods form stress when the refractive index glue is cured, which is easy to damage the optical fiber

In addition, the residual light in the cladding is stripped by corroding the inner cladding. Although this method does not have the problem of excessive local temperature of the optical fiber, this method needs to damage the inner cladding of the optical fiber, and the stripping efficiency is low. If more cladding light is to be stripped, It is necessary to increase the length of the stripper, resulting in reduced device reliability
