Abstract

The invention discloses an input optical fiber and a manufacturing method thereof, and an optical fiber beam combiner and a manufacturing method thereof, and relates to the technical field of opticalfiber lasers. The manufacturing method of the input optical fiber comprises the following steps of: preparing a multi-duct sleeve which can be processed by adopting a fused biconical taper method, wherein the multi-duct sleeve comprises a columnar body and a plurality of ducts arranged in the columnar body, and the plurality of ducts comprise a central duct located in the center and a plurality ofducts distributed in a ring shape, each beam of optical fiber penetrates one duct, the diameters of the optical fibers are matched with the inner diameters of the ducts; and carrying out fused biconical taper method processing on the multi-duct sleeve through which the optical fibers penetrate. The multi-duct sleeve is used for positioning the optical fiber in the whole manufacturing process of the input optical fiber, the position of the optical fiber is prevented from moving, the optical fiber is arranged uniformly, and the output loss of the pumping optical fiber is reduced.

Description

technical field [0001] The present application relates to the technical field of fiber lasers, in particular to an input optical fiber and a manufacturing method thereof, a fiber combiner and a manufacturing method thereof. Background technique [0002] The traditional process of making fiber optic combiner is as follows: [0003] 1. The pump optical fiber and the signal optical fiber are bundled together by knotting, and then heated by a hydrogen-oxygen flame to taper. In the process of fiber arrangement and knotting, it is easy to cause uneven arrangement, resulting in large output loss of the pump fiber after tapering and splicing the output fiber. [0004] 2. After the pump optical fiber and signal optical fiber are arranged, they are directly threaded into a quartz glass tube with a round hole, and then tapered by hydrogen-oxygen flame or laser heating. When the fiber arrangement is uneven, it will lead to a large output loss of the pump fiber after tapering and splic...
