Embodiment Construction

[0040] The present invention provides a novel capillary tapering method for fiber optic combiners, and develops a (N+1)×1 fiber laser pump combiner, which is mainly used to solve the problem of fiber laser pumping Combination problem, to achieve high-power semiconductor laser pumping of fiber lasers, different from the traditional fusion taper method, in this scheme, use quartz (or glass and other materials) capillary tubes as bundled fiber bundles (N tapered The multimode pump optical fiber and one transmission optical fiber are regularly stacked into a bundled fiber bundle) on the external frame, and the capillary is tapered, which realizes the overall tapering of the bundled optical fiber, and the bundled fiber bundle is fused with the capillary wall. As a whole, a tapered optical waveguide is formed to realize the combination of multiple laser beams.

[0041]After the tapering is completed, the bundled fiber bundle formed by N tapered multimode pump fibers and 1 signal tra...

Abstract

The invention relates to a production technology of an optical fiber combiner based on a capillary tube. The technology comprises the following steps of: 1) obtaining bundle fiber bundles; 2) bundling and arranging the bundle fiber bundles obtained from the step 1) by the capillary tube and forming the capillary tube which is internally embedded with the bundle fiber bundles; 3) carrying out beam combining treatment on the capillary tube internally embedded with the bundle fiber bundles obtained from the step 2) and forming a cone-shape optical waveguide. According to the invention, the production technology of the optical fiber combiner based on the capillary tube, which is convenient to fix and easy to taper, can greatly reduce energy loss in a laser combining process, and can improve a power bearing level of a beam combiner, is provided.

Description

technical field [0001] The invention belongs to the technical field of optical fiber coupling, and relates to a preparation process of an optical fiber combiner, in particular to a production method of a capillary-based optical fiber combiner. Background technique [0002] Optical fiber beam combiner (coupler) is a passive optical device that couples multiple laser beams into one optical fiber and synthesizes multiple laser beams into one optical beam, especially in the field of pump coupling technology for high-power fiber lasers, and optical beam combining of optical communication signals. Fields are essential key components. [0003] With the rapid development of the all-fiber process of high-power fiber lasers and the realization of kilowatt-level and 10,000-watt-level all-fiber lasers, higher requirements are placed on the load-carrying power level of the fiber combiner. There are new revolutions and technological breakthroughs in the field. [0004] The process prepa...
