More Information
Summary:The invention provides a three-branch tree-shaped photon lantern and a production method thereof. The three-branch tree-shaped photon lantern comprises N 3*1 sub photon lanterns which are distributed in a tree-shaped structure to form a multi-layer photon lantern structure, the output optical fiber of each 3 * 1 sub photon lantern in the upper layer of photon lantern structure is used as the input optical fiber of each 3 * 1 sub photon lantern in the lower layer of photon lantern structure; and each 3 * 1 sub photon lantern is formed by combining, tapering and cutting three input optical fibers and then welding the three input optical fibers with the output optical fiber. The multi-stage multi-aperture three-branch tree-shaped photon lantern can be manufactured according to any output optical fiber size, a possibility is provided for further achieving optical fiber laser output with higher power, larger mode field and higher light beam quality, and the three-branch tree-shaped photon lantern has wide applicat
