| 摘 要： | 本文阐述了受激喇曼放大的基本原理以及光纤传输中前向喇曼放大的分析计算方法,并着重介绍利用 Nd:YAG 激光器,在多模及单模光纤中进行的受激喇曼散射实验和喇曼放大实验.在这些实验中,得到了5级喇曼散射光谱,并实现了用光泵浦的方法放大弱光信号.利用受激喇曼散射研制光纤激光器以获得新频率的、可调谐的相干幅射,以及实现光纤中弱光信号的喇曼放大是很有前途的新方法.

| Abstract: | The fundamental principle of stimulated Raman scattering and mathe- matical analyses for forward Raman amplification are discussed in the paper. The remarkable experiments for stimulated Raman scattering and amplification in multimode and single mode fibers using Nd:YAG laser are also presented. In the experiments we obtained five order Raman scattering spectrum,achieved optical ampification for weak signals by pump.It is a significant and new me- thod with bright future to obtain tunable coherent emission as a fiber laser and realize Raman optical amplification. |
