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
