摘　　要：采用输出波长为975nm的LD通过锥形光纤束耦合器(TFB)泵浦15m长的Er3+/Yb3+共掺双包层光纤(EYDF),实现了全光纤型环形腔EYDF激光器。实验中,尝试了不同耦合比的耦合器作为该激光器的输出耦合器,当输出耦合比为99%时,得到了最佳实验结果:激光波长为1565.8nm,输出功率为1.07W,斜率效率为40%,光光转换效率达30.5%。All fiber ring cavity Er3+/Yb3+ co-doped double cladding fiber (EYDF) laser was achieved with 15 m long EYDF pumped by LD of 975 nm output wavelength through a taped fiber bundle (TFB). Six couplers with different couple ratio have been employed as the output coupler of the ring laser to optimize the experimental result. The best result is achieved when the output couple ratio is 99%; the laser output power is 1.07 W with the laser wavelength of 1565.8 nm, the slope efficiency and optic to optic conversion efficiency is 40% and 30.5%, respectively.
