本文报道了激光束在多种液体中自聚焦的实验结果。结果表明，光克尔效应和电致伸缩效应不能解释某些液体中自聚焦的温度变化。在这种情况下，前向受激布里渊散射似乎很重要。本文介绍了在液体中产生受激拉曼和布里渊辐射的测量结果。讨论了自聚焦和自陷对斯托克斯产生中前后向不对称性的影响。解释了受激拉曼和布里渊散射的其他定性特征。
Experimental results on the self-focusing of a laser beam in many liquids are reported. It is shown that the optical Kerr effect and electrostriction cannot explain the temperature variation of self-focusing in some liquids. Forward stimulated Brillouin scattering seems important in such cases. Measurements on the generation of stimulated Raman and Brillouin radiation in liquids are presented. The effect of selffocusing and self-trapping on the forward-backward asymmetry in the Stokes generation is discussed. Other qualitative features in the stimulated Raman and Brillouin scattering are explained.
