Description

technical field [0001] The invention relates to a high-precision and high-power optical fiber coupling laser lighting device, in particular to high-power laser lighting, and belongs to the field of laser lighting. Background technique [0002] Semiconductor lasers have the advantages of small size, easy pumping, high efficiency, and direct modulation. In recent years, with the continuous development of its technology, it has been widely used in pumping solid-state lasers, material processing, medical diagnosis and treatment, space communication, optical storage, etc. But it has a large divergence angle, horizontal and vertical The shortcoming that the divergence angle of the direction is very different, especially for high-power semiconductor lasers, the divergence angle of the two directions can be as high as 6:1, which brings great inconvenience to the use. [0003] For high-power semiconductor laser infrared long-distance lighting systems, on the one hand, the shape of t...

Problems solved by technology

For example, using a geometric lens combination collimation system can achieve a higher numerical aperture, but the processing requirements for components are relatively high, and the assembly and adjustment are more complicated; using an anamorphic prism to eliminate astigmatism and shaping system, it has perfect functions, but debugging and It is difficult to use; the coupling system with fiber optic microlens has high coupling efficiency, compact structure, and simple manufacture, but the small offset tolerance makes it difficult to adjust and unstable; based on the principle of light diffraction, diffraction processed by microelectronics technology Optical components, although they are small in size, light in weight, easy to replicate, and can realize wavefront transformation of arbitrary shapes, etc., are expensive to produce and do not take advantage of large-scale industrial applications
