| 摘 要： | 利用532 nm的脉冲激光进行了水和重水受激拉曼散射研究，不仅实现了O—H和O—D的伸缩振动受激拉曼散射，同时还实现了晶格振动的受激拉曼散射。水在激发光能量为130 mJ时出现低频受激Stocks和Anti-Stoks 313 cm-1谱线;重水在激发光能量为160 mJ时出现低频受激Stocks和Anti-Stoks 280 cm-1谱线。利用激光诱导等离子体解释了这种拉曼散射增强模式。

| Abstract: | Stimulated Raman scattering was studied in water and heavy water using pulse laser at the wavelength of 532nm, not only obtaining the stimulated Raman of O—H and O—D stretching vibration, but also obtaining the stimulated Raman lattice vibration. When the laser energy was 130 mJ, the low frequency Stokes and anti-Stokes 313 cm-1 line of water could be observed; When the laser energy was 160 mJ, the low frequnecy Stokes and anti-Stokes 280 cm-1 line of heavy water could be observed. The results were explained by physics mechanism of laser induced plasma. |
