有机液芯光纤拉曼谱测量的研究
Research of Raman Spectrum in Liquid Optical Fiber
摘要
我们选用CCl4和CS2混合溶液作为芯液制作了有机液芯光纤, 采用后向泵浦的方式测量了光纤的拉曼光谱。实验中发现, 随着溶质浓度和光纤长度的变化, 拉曼谱强度也随之变化, 并存在溶质最佳浓度和最佳光纤长度, 这与理论分析值相符, 并发现随着溶质浓度的降低, 拉曼光谱线宽变窄。
Abstract
We dissolved liquid CCl4 into CS2 and got different solutions of different concentrations. Raman spectrum can be obtained by Backward pump. The Raman intensity changes when the concentration and fiber length change. There exists the optimum concentration and optimum fiber length. Our experiment results are in good agreement with the calculated results. Raman linewidth becomes narrow when the concentration decreased.
