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...
