摘　　要：采用端面泵浦的方式,用尾纤输出波长为976 nm的高亮度多模半导体激光器,包层泵浦的铒镱共掺双包层大模面积光纤,非球面镜组耦合系统,进行了共掺双包层光纤的高功率L-band光纤激光器的研究,泵浦耦合效率达到了62%以上,并在F-P激光振荡腔中实现了高效的连续激光输出。在光纤长度为30 m、入纤功率为13.41 W时,首次报道输出连续功率达到了4.3 W。激光器的斜率效率为44%,激光输出中心波长1 603 nm。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 codoped 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 13.41W.
