| 摘 要： | An all-fiber Yb3+-doped double-clad fiber laser using FBGs as cavity mirrors is investigated in this paper. Continuous-wave (CW) output power of 1.18 W with defined wavelength at 1.06 um and narrow line-width of less than 0.1 nm is obtained. The slope efficiency and the maximum optical-to-optical efficiency of laser output are 68% and 51%, respectively, with respect to absorbed pump power.
