Fiber lasers have the advantages of high conversion efficiency, good beam quality, compact structure and convenient maintenance. In recent years, fiber lasers have been developed rapidly and have been widely used in scientific research, industrial manufacturing and national defense and safety fields. In the meantime, high power Laser development is one of the important directions. Fiber optic power combiner is the core component of high-power fiber laser. It can combine multiple medium-power fiber lasers to obtain higher-power fiber laser output and completely solve the problem of single-fiber laser due to nonlinear effect, Fiber end damage, thermal lens effects and other factors caused by the power bottleneck problem. Overcome the key technology of the optical fiber beam combiner, developed a high-efficiency and high-power optical fiber power combiner,
