对苯的长拉曼振动模式C—H(3060cm^-1线)伸缩振动的一阶受激拉曼散射进行了实验研究.利用在苯溶液中加入甲苯溶液,在液芯光纤内实现了苯的全对称C—H伸缩振动3060cm^-1线的受激拉曼散射.利用等离子体解释了这一增强机理.
In the paper we report on the enhanced stimulated Raman scattering of the weak-gain mode of benzene.The stimulated Raman scattering of C—H stretching vibration of benzene is observed in liquid core optical fiber by mixing toluene.The result is explained by(toluene-benzene)+ and(toluene-toluene)+ dimmer of plasma
