Abstract

The invention discloses a laser beam combining system and a hybrid laser beam combining system. The laser beam combining system comprises at least two input optical fibers, wherein each input optical fiber is provided with at least one tapering uniformizing section, and the input optical fibers form an integrated structure at the tapering uniformizing sections. Each tapering uniformizing section comprises a cylindrical fusion portion located in the middle and tapering truncated-cone portions connected to two ends of the cylindrical fusion portion. The laser beam combining system and the hybrid laser beam combining system breaks through optical device limitations of spatial beam combination, and light source miniaturization and multi-wavelength integration are very easy to achieve. In addition, high-quality light beam output is very easy to achieve through multiple times of uniformized light mixing processing, and light spot rules, chromatic dispersion and speckles are well controlled.

Description

technical field [0001] The invention relates to laser technology, in particular to a laser beam combining system and a laser composite beam combining system. Background technique [0002] As a special light source, laser is widely used in laser display, special lighting, biomedical equipment, stage demonstration, military and police equipment and other fields. In the prior art, the energy of a single laser beam is relatively limited. In order to obtain high-power laser beams, multiple laser beams are often combined by a laser beam combining device. [0003] Laser beam combining devices in the prior art include single-wavelength high-power lasers and multi-wavelength composite high-power lasers. Among them, single-wavelength high-power lasers are mostly formed by combining semiconductor lasers in space, with poor beam quality and irregular output spots. Speckle is serious, and limited by the principle of single-wavelength light combining and optical light combining devices, ...
