However, the common laser light sources are bulky and poorly sealed, which greatly reduces the service life of the light source.
In addition, most lasers use a hard optical path output, which cannot meet the requirements for light sources in complex environments

Embodiment Construction
[0019] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] A single-fiber laser light source coupling system includes a laser light source array, and the laser light source adopts an LD light source or other frequency-doubled light sources.
[0021] Such as figure 1 As shown, the LD light sources described in this embodiment are neatly arranged in a 2*4 manner, that is, a total of 2 columns, divided into 4 groups; a right-angle prism is arranged directly above each group of laser light sources, and a total of four right-angle prisms are required. Each right-angle prism reflects the laser light emitted by a group of LDs. The height of the four right-angle prisms increases step by step and is arranged in a ladder shape. The emitted light does not emerge from the rectangular prism, and the reflected beams do not interfere with each other. figure 1 Among them, the first rectangular prism 201 is l...

The invention provides a laser light source fiber coupling design comprising an LD, a rectangular prism, a reflecting mirror, a wave plate, a PBS block prism, a convergence lens, a fiber jumper and other matched metal support devices. Laser light beams emitted by the LD light source are applied, and four light beams reflected by the rectangular prism and four light beams through the rectangular prism, the wave plate and the reflecting mirror are coupled into a group of light by using the beam combining effect of the block prism and then coupled into one fiber jumper through convergence of the convergence lens. The design is simple in mechanism, great in system sealing performance, high in stability, high in optical power density and easy to integrate. The design uses single fiber for coupling so as to have a quite wide use direction.
Description
technical field [0001] The invention relates to laser coupling technology, in particular to a single fiber laser light source coupling system, which is applied to the field of laser light source, especially the field requiring high power density single fiber output. Background technique [0002] At present, there are already some laser light sources and laser coupling solutions on the market, which are used in lighting, stage lighting and test instruments. However, the common laser light sources are bulky and poorly sealed, which greatly reduces the service life of the light source. In addition, most lasers use a hard optical path output, which cannot meet the requirements for light sources in complex environments. Therefore, a new coupling scheme is proposed to realize the miniaturization of the light source, solve the sealing problem, and complete the soft optical path coupling. Contents of the invention [0003] The purpose of the present invention is to propose a las...
