Embodiment Construction

[0037] The above and other technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0038] In one embodiment, such as figure 1 shown. This embodiment provides a bar integration for semiconductor lasers, which includes a bar positive plate 1 , a bar negative plate 2 , a mirror chamber 3 , a light source 4 , a waveguide plate 5 , and an FAC mirror 6 . Wherein, the positive electrode plate 1 of the bar bar and the negative electrode plate 2 of the bar bar are attached to each other in the direction of the fast axis, and the direction a in the figure shows the direction of the fast axis. It should be noted that the direction a in the figure only shows a single direction. In fact, both the a-direction and the opposite direction to the a-direction are the fast axis directi...

Abstract

The present invention provides a bar assembly for a semiconductor laser. The bar assembly includes a bar positive pole plate, a bar negative pole plate, a mirror surface chamber, a light source, a waveguide sheet, and an FAC mirror; the bar positive pole plate and the bar negative pole plate are attached to each other in a fast axis direction; the mirror surface chamber is formed between the bar positive pole plate and the bar negative pole plate, and is open in a slow axis direction; the light source, the waveguide sheet, and the FAC mirror are sequentially disposed in the mirror surface chamber along the slow axis direction; the FAC mirror covers an opening of the mirror surface chamber which is open in the slow axis direction.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to bar integration for semiconductor lasers. Background technique [0002] Generally, the semiconductor laser array is composed of multiple light-emitting points. After simple optical imaging and shaping, the total beam distribution is still strong and weak, and the distribution is not uniform enough. For this reason, there is a patent application with publication number CN106941240A to disclose a semiconductor laser, which makes the light spot formed on the slow axis direction uniform by arranging BAR strips, FAC mirrors, focusing lens groups, waveguide plates, and imaging lenses in the slow axis direction. change. Moreover, the size of the image point is n times larger than the size of the luminous point, which increases the energy area. In fact, it mainly uses the focusing lens group and the waveguide plate to homogenize the light spot and enlarge the size of the image point. ...
