| 摘 要： | 计算了等离子体拍频波加速器中双频抽运光与Langmuir波的相互作用及其时间发展。指出Langmuir波出生成到饱和的过程,与三波位相由匹配到失配密切相关。三波位相差作为描写三波耦合程度的量对于双频激光激发Langmuir波至关重要。

| Abstract: | The interactions of two-frequency laser with Langmuir wave in a plasma beat-wave acce-lerator are calculated. We show that the development of the Langmuir wave from initial stage to saturation is closely correlated to the evolution of the three waves involved from phase locking to phase mismatching. The phase difference, describing the extent of three-wave coup-ling, is therefore of great importance in Langmuir-wave excitation by beating two-frequency la-ser. |
