    • 摘要

      针对分布反馈式光纤激光器(DFB-FL)线宽特性进行了深入研究.通过理论推导和实验验证, 分析了自脉动、相 移光栅、激射窗口宽度以及外界环境扰动等因素对DFB-FL线宽的展宽作用. 进一步提出了压缩DFB-FL线宽的有效方法和途径,给出了自注入锁模方式下对DFB-FL线宽压缩的对比实验结果, 将DFB-FL的线宽从35 kHz压缩到了10 kHz.

      Abstract

      The linewidth characteristics of distributed feedback fiber laser (DFB-FL) is fully explored in this paper. The linewidth broadening effect of DFB-FL induced by self-pulsation, phase-shifted grating, especially lasing window, external disturbance, etc. are extensivly investigated in the paper based on the theoretical derivation and experiment. An effective linewidth compression method is proposed, and a self-injection system of DFB-FL comes up to reduce its linewidth from 35 kHz to less than 10 kHz.
