【摘要】 随着光纤在生产和科研上的运用的日益广泛,有必要对光纤中的一些物理效应进行深入而广泛的研究。光纤的受激喇曼散射(SRS)效应就是主要研究内容之一。 本文首先对石英系单模双折射光纤的传输光偏振特性进行了测试和分析。其次在实验上和理论上对双折射光纤中的受激喇曼散射的光谱特性进行了系统研究,分析了各级喇曼谱的频移,谱宽和各级喇曼谱的阈值。第三,对SRS的传榆模式进行了探讨,理论分析和实验结果基本符合。

【Abstract】 Stimulated Raman Scattering (SRS) is a kind of common phenomenon in the optical fiber .With the wide application of the optical fiber in experiment and in practice , SRS has become an subject researched.In the paper , a experimental method was devised to measure polarizing character of propagating light in the birefringence optical-fiber and an analysis of it was made. The research is mostly concentrated on the spectrum quality of SRS in the birefringence fiber, then making a systematic analysis of SRS both in experiment and in theory ,at the end of the paper drawing some conclusions.
