Abstract

The invention discloses a laser beam combination device, which comprises a main reflecting mirror, a first beam combination mirror, a first collimator, a dichroic mirror, an achromatic lens, a diaphragm, a second beam combination mirror, a second collimator, a first laser generation assembly and at least one second laser generation assembly, wherein the second laser generation assembly is used for emitting second laser and irradiating to the main reflecting mirror, and light reflected by the main reflecting mirror gets into the first beam combination mirror, then gets into the first collimator and forms transmitted light through being transmitted by the dichroic mirror; the first laser generation assembly is used for emitting first laser and irradiating to the dichroic mirror, the first laser is reflected by the dichroic mirror to form reflected light, the transmitted light and the reflected light are combined into output light through the dichroic mirror, and the output light sequentially passes through the achromatic lens, the diaphragm, the second beam combination mirror and the second collimator. The laser beam combination device not only can perform beam combination on light beams with two types of wavelengths, but also is high in power of the output laser.

Description

technical field [0001] The invention relates to a laser beam combining device, belonging to the technical field of lasers. Background technique [0002] At present, the advantages of high efficiency, long life, small size and light weight of semiconductor laser make it have a wide range of application prospects. However, limited by the quality of the beam, it is difficult for semiconductor lasers to be used as direct light sources in fields that have high requirements for power, beam quality and brightness. In response to this problem, a series of research on how to improve the power, power density and beam quality of semiconductor lasers has been carried out internationally, and laser beam combining technology has emerged as the times require. However, the existing semiconductor laser fiber beam combining and coupling output technology has one of the biggest disadvantages, that is, it is impossible to achieve high-power coupling output under the premise of maintaining the ...
