Description

technical field [0001] The invention relates to the field of optical coupling technology, in particular to a configurable optical fiber bundle combiner. Background technique [0002] As the market's requirements for the power and efficiency of fiber lasers continue to increase, fiber lasers are also developing in the direction of higher power, longer life, and lower cost. However, due to the influence of its manufacturing process and materials, the power of a single fiber laser is getting closer and closer to the limit value, and it is difficult to make further breakthroughs. [0003] In order to increase the power of the laser, the light output by multiple fiber lasers is usually combined to form a beam of laser light, thus a fiber combiner appears. At present, the beam combining methods of common fiber combiners include all-fiber coupling and spatial mirror coupling. All-fiber coupling must fuse multiple fibers together, which is inconvenient for operation and later main...

Problems solved by technology

All-fiber coupling must fuse multiple fibers together, which is inconvenient for operation and later maintenance

Spatial mirror coupling means that the output light of multiple fiber lasers is reflected, refracted and focused by various mirrors to form a laser beam. The arrangement of multiple mirrors needs to occupy a large volume, resulting in an excessively large volume of the fiber combiner

[0004] To sum up, the optical fiber combiner in the prior art is either inconvenient to operate and maintain in the later stage, or it is too large to meet the needs of users well. There is an urgent need for a new type of optical fiber combiner
