[Abstract]:Because of its simple and compact structure, high integration, good stability, good heat dissipation, good output laser beam quality, beam tunable and so on. Since its emergence, it has become a hot spot in laser field. With the improvement of industrial manufacturing level. The demand for output power of fiber laser is more and more high. In this paper, the high power fiber laser is studied and explored from two aspects: theoretical simulation and end cutting experiment. The advantages and characteristics of fiber laser are introduced, and the high power characteristic of fiber laser is simply described from two aspects: the basic theory of fiber and the basic theory of fiber laser. The energy level structure and spectral characteristics of Yb3 ion are introduced. The basic theory of ytterbium-doped double-clad fiber laser is studied based on the rate equation. The ytterbium-doped fiber used in the laboratory is simulated by Matlab software, and the output power characteristics of the laser under three pumping modes are compared. In order to obtain higher pump efficiency, the theory of fiber end surface treatment is studied, the treatment method of fiber end surface is introduced, and the brittle fracture theory in fiber end face is discussed. The morphology and characteristics of the fiber end face are briefly introduced. The characteristics and application methods of LCC 鈪，
