| 摘 要： | 提出和证实了一种光纤环形激光器. 将一个带通滤波器与一个带阻滤波器级联,用一段保偏掺铒光纤作为饱和吸收体,得到了一种单纵模双波长光纤激光器. 结果表明,该激光器波长间隔为0.4 nm,边模抑制比大于49 dB.如果将两个波长进行差拍,该激光器有潜力得到49.85 GHz的微波信号. |

| Abstract: | A fiber ring laser was proposed and demonstrated. By cascading a bandpass filter with a bandstop filter and employing a polarization-maintaining erbium-doped fiber as a saturable absorber, a single-longitudinal-mode dual-wavelength fiber ring laser was achieved. The results show that the wavelength spacing is 0.40 nm and the side-mode suppression ratio is greater than 49 dB. The proposed laser has potential to generate microwave signal of 49.85 GHz by heterodyning the two wavelengths. |
| Keywords: | Fiber ring laser Dual-wavelength Single-longitudinal-mode Filter cascade Saturable absorber |
