| 摘 要： | 从理论上分析了激光被聚焦到高压气体内可能发生各种非线性现象的规律及其相互作用和相互干扰.在实验中把Nd:YAG四倍频激光聚焦到充有甲烷的拉曼管内,测各阶斯特克斯光输出能量与气压pa、透镜焦距f和输入能量Ep之间的关系.实验结果与理论分析定性地相符合，这就为我们优化和利用受激拉曼过程提供了理论和实验依据.

| Abstract: | This paper analyzes theoretically various nonlinear phenomena caused by focusing a laser beam into high pressure gas, and the interaction and interference produced, measures the relationship among output energy, input energy, gas pressure and focal length when the fourth harmonic Nd:YAG laser is focused into the Raman cell filled with methane. Experimental results are in agreement with theoretical ones qualitatively. Based on these we can optimize and use the stimulated Raman scattering. |
