| 摘 要： | 本文研究了激光拍频波加速器中的三波相互作用过程。结果表明:适当地选择参数σ=ωp/(ω1-ω2)以及β=ω2/ω1(ωp,ω1,ω2分别为等离子体频率及两束激光频率),即可用较弱的激光造成很强的拍频等离子体波,并使注入等离子体的电子获得显著的能量增益。关键词：

| Abstract: | The three-wave interaction in a laser beat-wave accelerator are studied. We find that with the parameters of σ = ωp(ω1-ω2) and β=ω2/ω1 properly chosen (where ωp, ω1, ω2 are the plasma frequency and frequencies of the two laser beams respectively), the required large-amplitude plasma wave will be excited even though the incident laser beams are relatively weak. As a result, the injected electrons will get a sighificant energy gain. |
