The EDF is used to provide both nonlinear and linear gains to generate a stimulated Brillouin scattering （SBS） and to amplify the generated SBS, respectively. The Brillouin erbium fiber laser （BEFL） operates at 1561.5 nm, where the operating wavelength is up-shifted by 0.08nm from the Brillouin pump. The operation wavelength is also tunable within 1560.6-1562.6nm. The BEFL Mso shows a self-pulsing characteristic with repetition of 66. 7kHz when the BP is set around the threshold pump power of 13roW. Compared to the conventional Brillouin fiber laser with a long cavity length, the proposed BEFL exhibits a significantly lower amplitude of pulse. This laser has many potential applications, such as in optical communication and sensors.展开更多
