摘要

Perlin等[1]提出了基于长均匀光纤布拉格光栅构建分布式反馈光纤拉曼激光器的可行性。然而，这种激光器需要在很长的长度上(例如1m)具有良好的光栅均匀性，并且尚未进行实验研究。在这项研究中，我们展示了一种改进的DFB光纤拉曼激光器设计，该激光器具有优化的λ/4相移光栅结构，可以在低阈值下以相对较短的腔长实现高效的激光操作。

Design of λ/4 phase shifted DFB fibre Raman laser

The feasibility of building a distributed feedback fibre Raman laser based on a long uniform fibre Bragg grating was suggested by Perlin et al. [1]. However, such a laser requires good grating uniformity along a very long length, e.g. 1m, and has not been investigated experimentally. In this study, we demonstrated an improved design of a DFB fibre Raman laser with an optimised λ/4 phase-shifted grating structure, which enables highly efficient laser operation at low threshold with a relatively short cavity length.
