A end-pumped co-doped double-clad high-power fiber laser in L-band was studied using a 976 nm pigtailed multimode tunable high brightness diode laser
clad-pumped erbium-ytterbium co-doped double-clad large-mode-area (LMA) fiber and the aspheric lenses coupler. The pumping coupling efficiency is more than 62% and the high efficiency continuous wave laser is gained in the Fabry Perot cavity. The experimental results show that a Er/Yb co-doped double clad native large-mode-area fiber laser can get output power of 4.3 W and the slope efficiency of 42% at signal central wavelenth of 1603 nm
when the double-clad fiber length is 30 m
the pumping power of entering fiber is 13.41 W.
