【Abstract】 In this paper,high power Yb-doped double-clad fiber( DCF) lasers with Fabry-Perot( F-P) laser cavity are studied in theoriesand experiments.Deriving from the rate equationsmodel of fiberlasers,wegetthe explicitexpressions of outputpowers,slope-efficienciesand thresholdsof fiberlasers.We focusourdiscusson F- P cavity and getsome valuable results.A maximum cw outputpowerof 1 0 .6W,and slopeefficiency of 86% are observed with the Yb-doped D-shaped double-clad fiber laser in experiments.Also experimental results are coincidentwith theoretical analysis.更多还原
