Multi-core fiber laser coupling device

The utility model belongs to the technical field of laser, and discloses a multi-core fiber laser coupling device. The multi-core optical fiber laser coupling device comprises at least two laser emitters, an optical fiber beam combiner, an incident optical fiber and an emergent optical fiber, each laser emitter is installed at one end of the incident optical fiber, and the other end of the incident optical fiber converges into the emergent optical fiber through the optical fiber beam combiner to achieve superposition of laser to form a beam of superposed laser. When the high-power laser is used, laser emitted by each laser emitter sequentially passes through incident light and the optical fiber beam combiner to be converged into one emergent optical fiber, and because the laser passes through the optical fiber beam combiner, the laser emitted from the emergent optical fiber is a beam of superposed laser, so that high-power output of the laser is realized. 本实用新型属于激光技术领域，公开了一种多芯光纤激光耦合装置。该多芯光纤激光耦合装置包括至少两个激光发射器、光
