摘　　要：在对激光产生的等离子体做等温膨胀的假定下 ,应用解析方法研究了紫外强激光脉冲辐照金属靶材时 ,计及等离子体再辐射对激光 靶材耦合效应的影响。其结果与有关实验数据相一致 ,合理地解释了实验结果。In the hypothesis of plasma isothermal expanding, enhanced effect of radiation coupling induced by laser-generated plasma on aluminum target is studied analytically. The calculation results have demonstrated the significance of plasma re-radiation in interaction of powerful pulsed laser with metal target. These results agreed with experimental data well, and explained the experimental results theoretically.
