摘要: 讨论了光纤光栅法布里-珀罗(F-P)标准具选模光纤激光器的单频运转原理，并研制了全光纤结构单频掺Er3+光纤环形激光器。实验中采用两个976 nm激光二极管双向泵浦作为泵浦源，高掺杂浓度掺Er3+光纤作为增益介质，以行波腔消除空间烧孔效应，利用光纤光栅F-P标准具窄带选模特性，当泵浦光功率为36 mW时，得到了稳定的单频激光输出。实验中使用了长5和3 m的掺杂光纤，在泵浦光功率为145 mW时输出功率分别为19和42 mW，光-光转换效率分别为13%和29%，斜率效率分别达到了16%和33%。输出谱线3 dB带宽0.01 nm，无跳模现象。Abstract: The principle of single frequency operation of the fiber laser with mode selected with fiber Bragg grating Fabry-Perot etalon is presented. The all-fiber single frequency Er3+-doped fiber ring laser has been designed in which two 976 nm laser dodes are used as the pump sources, the high concentration Er3+ -doped fiber as the gain medium, the travelling cavity is adopted to eliminate the spatial hole burning effect. The designed etalon can discriminate and select laser longitudinal modes efficiently and a stable single-frequency laser is obtained. The experiment using 5 m and 3 m long Er3+-doped fibers respectively is presented. When the maximum pump power is 145 mW, the output powers are 19 mW and 42 mW respectively and the optical-optical conversion efficiency are 13% and 29%, the slope e
