在激光韦克菲尔德加速实验中，研究了超短强激光脉冲的受激拉曼侧向散射。实验和模拟表明，受激拉曼侧向散射发生在相互作用的开始阶段，它在韦克菲尔德形成之前对脉冲的演化有贡献，并且影响所产生电子束的质量。测量了等离子体频率的相对论位移。
Stimulated Raman side scattering of an ultrashort high power laser pulse is studied in experiments on laser wakefield acceleration. Experiments and simulations reveal that stimulated Raman side scattering occurs at the beginning of the interaction, that it contributes to the evolution of the pulse prior to wakefield formation, and also that it affects the quality of electron beams generated. The relativistic shift of the plasma frequency is measured.
