Paper Abstract

Based on requirement of all fiber structure, all fiber Yb-doped fiber grating laser uses double cladding fiber with Yb-doped as gain medium, uses fiber grating as resonance cavity and employs semiconductor laser as pumping source to realize the lasing based on the reverse of Yb ion. 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 7.5W single-mode laser output, central wavelength of 1080nm, FWHM of 0.11nm under the pump power of 11.8W. Maxim conversion efficiency is 63.5% and slope efficiency of 46.4%.
