Abstract

The invention discloses a novel royal purple laser light source which comprises a plurality of light-emitting sets, each light-emitting set comprises a laser diode, laser emitted by the laser diodes enter the input end of a lens set which is used for compressing the divergence angle of the laser in the fast axis direction, the output end of the lens set is provided with an optical fiber ball lens which is connected with a fiber core, and the fiber core is connected with an optical fiber bundle insert core. A plurality of the laser diodes with small power are coupled with the optical fibers respectively and finally are bundled to form the royal purple laser light source with high power, the novel royal purple laser light source has the advantages of being high in coupling efficiency, high in stability of generated laser, even in distribution of light spots, and the like, and the problem that the end faces of the optical fibers are easily burned after a short-wave long light source is coupled with the optical fibers is solved.

Description

[technical field] [0001] The invention relates to a novel blue-violet laser light source. [Background technique] [0002] Most of the traditional ultraviolet light sources are high-pressure mercury lamps or excimer lasers. Because the high-pressure mercury lamp is not only not environmentally friendly, but also has a short life and high power consumption; while the excimer laser is too expensive and bulky. [Content of the invention] [0003] The present invention overcomes the deficiencies of the above-mentioned technologies, and provides a novel blue-violet laser light source, through which a plurality of low-power laser diodes are respectively coupled with optical fibers to form a high-power blue-violet laser light source, which has high coupling efficiency and high laser output. It has the advantages of high stability and uniform spot distribution, and at the same time solves the problem that the end face of the fiber is easily burned after the short-wavelength light s...
