| Abstract: | A double-clad Yb 3+ doped fiber laser is made when choosing fiber grating as resonator and pumped by LD fiber-coupled modules, with tapered fiber to get all-fiber structure. Fusion is often adopted to incorporate the fiber grating with the double-clad fiber, and the inner-cladding shape of double-clad fiber (DCF) is quasi-circular shape of Yb 3+ doped silica fiber with 970 nm center wavelength of fiber output modules as pump source. When the current of pump source is 2.4 A, the single-tranverse-mode output with max output power of 10.8 W is obtained with FWHM of 0.54 nm at output wavelength of 1100.5 nm, and the slope efficiency of 59% is observed. |
