摘要
本论文对可调谐光纤激光器做了简要综述，对可调谐掺铒光纤激光器进行
了理论分析和实验研究，文章最后还对超荧光光纤光源进行了理论分析和实验
研究。具体做了以下工作：
1 首先在第一章介绍了光纤激光器的分类及其工作原理，以及可调谐激光
器的发展现状。
2 论文在第二章介绍了可调谐半导体激光器的工作原理，以及用于可调谐
光纤激光器的可调谐滤波器的工作原理。论文还在此章着重介绍了 F-P 滤波器
的工作原理，特性参数以及级联 F-P 滤波器的性能和基本结构，并分析计算了
一个应用的例子。
3 在第三章中，首先介绍了掺铒光纤激光器的设计原理，又分析了掺铒光
纤激光器工作在 L 波段的原理。利用楔形膜可调谐滤波器，自制的 F－P 角度
调谐滤波器，以及保偏光纤环形镜分别作为调谐装置，设计了 C 带可调谐掺
铒光纤激光器，并进行了实验研究。利用楔形膜可调谐滤波器获得了最佳输出
效果，调谐范围是 1528nm-1563nm，覆盖了大部分 C 带，激光输出功率可达
1mW，线宽可达 0.094nm。
4 此外，还设计了利用保偏光纤环形镜作为调谐装置的 L 带可调谐光纤激
光器，并进行了实验研究。其中双级泵浦 L 带可调谐光纤激光器和加入 FBG
的 L 带可调谐光纤激光器获得了理想的效果，可调谐范围从 1565nm-1615nm，
基本覆盖了整个 L 带，激光的输出功率大于 1mW，线宽在 0.6nm 左右。
5 在最后一章，首先分析了光纤超荧光的产生原理及其基本结构，接着设
计了 L 带以及宽带超荧光光源，并进行了实验。得到的 L 带超荧光输出的 3dB
带宽从 1565nm-1610nm；宽带超荧光输出的 3dB 平坦度内的带宽从
1550nm-1607nm，其总的转换效率为 12.3％。

are tuned by PMF-FLM. Among them, the ideal outcomes obtained by double
pumped structure and the structure with a FBG. The tunable range is 1565nm-1615nm,
which is almost cover entire L-band. The output power is more than 1mW and the
bandwidth is about 0.6nm.
