中文摘要：

采用FP腔结构研究了包层泵浦掺Yb^3＋微结构光纤激光器的输出特性。在以二向色镜作为腔镜的实验中，获得了斜率效率57％，波长1074．5nm，输出功率为2．65W的稳定激光输出；在由二向色镜和光纤端面构成F-P腔的实验中，获得了斜率效率87％，最大输出功率为11．69W的激光输出。

英文摘要：

A high power air cladding pump microstructure fiber laser with output power exceeded 10 W was demonstrated using Fabry-Perot resonance cavity configuration. The output power and slope efficiency of the double clad ytterbium-doped large mode-area microstructure fiber laser are 8.38 W and 87% ,respectively, and the highest output power can achieve to 11.69 W.
