Abstract

The invention is a linear light beam shaper, belonging to optical component field. It is composed of above two mircoprisms dislocated and closely arranged, each microprism has three all-reflecting surfaces, N microprisms change the light beam into N vertical closely-arranged light beam groups, the distance between the light beam groups can be controlled by the difference of optical distance of the light beam between the first and second reflecting surfaces of the two adjacent microprisms and after shaped, the light beam does not change the advancing direction. It has compact structure, convenient processing and film plating, simple and convenient to install and clamp and high shaping efficiency, and other characters.

Description

technical field

[0001] The invention relates to a linear beam shaper composed of transmission elements. It is mainly used in the beam shaping of linear light-emitting devices of semiconductor lasers, and improves the focusing and coupling performance of the beam by changing the shape and spatial distribution of the beam, and belongs to the field of optical components. Background technique

[0002] With the development of semiconductor integration and assembly technology, the power of semiconductor lasers has been greatly improved in recent years. High-power semiconductor lasers have two main uses: one is directly used as a laser source, such as in beauty, medical treatment 1. Applications in material processing; 2. Pumping solid-state lasers or fiber lasers as pump sources to replace lamp-pumped solid-state lasers, which have been widely used in industrial processing, material processing, medical beauty and military industries. Since the semiconductor laser has an extremely...
