【摘要】 利用Nd :YAG锁模序列脉冲激光 (10 6 4nm)抽运充有高压H2 的拉曼池 ,输出光束经棱镜分光后投射在屏上 ,在可见光及近紫外光区用彩色胶卷摄得 15个受激拉曼散射光斑 ;经 1m光栅摄谱仪摄谱 ,在 36 5— 6 0 5nm波长范围内得到 6 5条受激拉曼谱线 .通过实验结果与理论计算值的比较 ,证明除了H2 的振动拉曼频移量 4 15 4 6cm- 1 外 ,还有多个振动及转动拉曼频移量共同参与作用 ,从而产生了从紫外到红外众多波长的受激拉曼散射光 .更多还原

【Abstract】 This paper reports the fact that 15 Raman scattering faculas in the range of visible light are observed, which are generated by pumping a Raman cell filled with high-pressure H 2 with a model-locking Nd:YAG laser at 1064nm.The output laser is dispersed by a prism, so we can see the faculas behind the prism. Sixty-five scattered lines can be found in the range of 365nm-605nm if the output beam is dispersed by a grating spectrograph. By numerical analysis, it is shown that other vibrational Raman shifts and rotational Raman shifts are stimulated, besides the vibrational Raman shift at 4154.6cm -1. They all cause the multi-wavelength stimulated Raman scattering light, which show up from ultraviolet to infrared realm.更多还原
