Paper Abstract

Erbium-doped fiber laser has many excellences, such as narrow bandwidth and long range to tune. It could be used in DWDM communication and sensing. We focuse on erbium-doped fiber laser, because it radiates at 1550nm lying in 3 rd window of low loss in fiber-optic communications. In this paper, by studying erbium-doped fiber ring laser's theory and using simulation method, we have obtained many key laser parameters, and designed a high efficiency erbium-doped fiber ring laser with a fiber Bragg grating used as filter .When the pump power is 150mW, a ring-cavity all-fiber laser worked at 1550.285 nm has been demonstrated with an output power of 45 mW and a bandwidth of 0.05 nm at 3dB. Its pumping efficiency is 30%. In the design, we have adopted many kinds of methods to stabilize its power. Finally the power stability is 0.20%. Such laser is suitable for communications and sensing.
