| 摘 要： | 本文导出了法向入射时,双频激光辐照的等离子体中的稳态电场强度和局域标度长度的解析表达式。结果表明,双频辐照的有质动力可以导致临界面附近出现密度凹坑和临界密度处的局域标度长度在某个强度范围内的反常增加和起伏。关键词：

| Abstract: | The analytic expressions for steady-state electric field intensity and local scale length in a plasma irradiated by doublefrequency laser are derived. It is shown that the ponderomotive force due to double-frequency laser field would lead to the local density dip near critical surface and the anamolous increase and fluctuation of the critical scale length in some region of field intensity value. |
