We use Bragg fiber grating as the resonance cavity of fiber laser and 970nm LD as pumping source  pump the Yb-doped double cladding fiber with circular inner-cladding. We realized 7.5 W single-mode laser output  central wavelength of 1080nm  FWHM of 0.11 nm under the pump power of 11.8W. Maxim conversion efficiency is 63.5 % and slope efficiency of 46.4%.
