Abstract

The invention discloses a light spot homogenizing device. The light spot homogenizing device comprises an optical fiber, wherein the optical fiber comprises an input end socket, an output end socket and a homogenized optical fiber formed by heat treatment; an optical fiber protecting sleeve is sleeved outside the optical fiber; the output end socket of the optical fiber is provided with an optical fiber tail sleeve; an optical fiber heat shrinkable tube is arranged on the homogenized optical fiber of the optical fiber. The invention further discloses a manufacturing method of the light spot homogenizing device. The manufacturing method comprises the steps of stripping a coating layer on the optical fiber; carrying out heat treatment on the optical fiber part without the coating layer, wherein the temperature is 1300-1500 DEG C; after enabling the optical fiber without the coating layer to reach a fused state, cooling the optical fiber; covering the optical fiber protecting sleeve on the whole optical fiber and covering the optical fiber tail sleeve on the output end socket of the optical fiber; fixing the optical fiber of the heat treatment part by using the optical fiber heat shrinkable tube. The light spot homogenizing device is good in homogenizing effect and the manufacturing method is simple and convenient; the problem that output light spots of a semiconductor laser device are not uniform is solved effectively.

Description

technical field [0001] The invention relates to a light spot homogenizer and a manufacturing method thereof. Background technique [0002] A semiconductor laser is a device that produces stimulated emission by using a certain semiconductor material as a working substance. Its working principle is to realize the particle number inversion of non-equilibrium carriers between the energy bands of the semiconductor material, or between the energy band of the semiconductor material and the impurity energy level, through a certain excitation method. When a large number of electrons and holes in the state recombine, stimulated emission occurs. At present, the output spot distribution of optical fiber-coupled semiconductor lasers on the market is uneven, and it is easy to appear rings, dark centers, etc., which limits the use of semiconductor lasers. Contents of the invention [0003] The object of the present invention is to address the above problems, to provide a light spot hom...
