摘　　要：利用F-P谐振腔实验研究了高功率掺Yb3+光子晶体光纤激光器。使用915 nm和976 nm两种波长的泵浦源进行双端泵浦,在23 m长的双包层光子晶体光纤中获得了552 W的连续单模激光输出。该激光器的斜率效率约为76%,光-光转换效率为56%,光谱中心波长为1078 nm,光束质量平方因子为1.2。A high-power Yh^3＋-doped photonic crystal fiber（PCF） laser based on Fabry-Perot cavity structure was studied. The laser was two-end pumped by two pumping sources at 915 nm and 976 nm, respectively, and a single-mode continuous-wave laser of 552 W was obtained. The laser had a slope efficiency of 76% and an optical-to-optical conversion efficiency of 56%. The central wavelength of the laser was 1 078 nm and the beam quality factor was 1.2.
