摘要
Yb-doped double-clad fiber amplifiers of different lengths were pumped by a fiber-coupled diode laser emitting at 976 nm. A non-planar ring oscillator was used as the signal source emitting CW single frequency radiation at 1064 nm. When the pumping power was 49.6 W and the signal power was 200 mW, up to 16.1 W single-frequency laser was obtained in a 10 m-long fiber. The relation between fiber length and output power was analyzed by changing different lengths of fiber as the gain media. The emission spectrum was discussed. Single frequency operation was verified by a Fabry-Perot interferometer.
