摘要
The single-polarization distributed-feedback (DFB) fiber laser at 1053 nm by stress-induced phase-shift birefringence is demonstrated and the corresponding theoretical analysis is given. The polarization extinction ratio of the DFB fiber laser is about 14 dB. And the DFB fiber laser has directional output due to the phase shift region deviated from the center of the fiber grating.
