摘　　要：介绍了一种基于商用掺铒光纤放大器、光纤布拉格光栅和可变光衰减器的可调谐、超稳定、窄带宽光纤激光器的实现方案及性能。研究结果表明,该光纤激光器的输出功率稳定性好(1h之内的稳定度<0.92%),线宽窄(<52pm),边模抑制比高(约30dB),调谐范围超过20nm。整个系统不仅可以用作窄带宽光纤激光器,还可以作为宽带自发辐射输出光源和掺铒光纤放大器,且该系统易于实现,很容易在普通实验室里搭建。This paper introduces the performances of an ultrastable tunable narrow-band fiber laser and its implementation scheme.Based on the commercially available Er-doped fiber amplifier,fiber Bragg grating and variable optical attenuator,this fiber laser has high output power stability（＆lt;0.92% within one hour）,narrow linewidth（＆lt;52pm）,high sidemode suppression ratio（~30dB）and large tunable range（over 20nm）.The entire system can not only be used as a narrowband fiber laser but also as a wideband amplified spontaneous emission light source and an Er-doped fiber amplifier.Furthermore,this system can be easily realized in an ordinary laboratory.
