摘要: 采用一维流体动力学模型,以烧蚀压力作为已知的边界条件,分别以解析和数值计算方法,描述了短脉冲强激光辐照固态铝、铜和碳酚醛靶材时,烧蚀加载在靶材中产生的激波的增强、持续和衰减过程,给出了激波峰值压力和波形等特征参数的时空关系。

关键词: 强激光效应, 烧蚀加载, 靶材中激波传播特性

Abstract: A numerical method and an analytical method for study creation and decay of laser generated shock-wave in the target are presented on the basis of one-dimensional hydrodynamic model.The ablation presure is used as boundary condition.These methods permit the caculation of the three stages of shock-wave evolution.Three kinds of solid state material,such as Al,Cu and C/Ph are caculated.The maximum presure and shock-wave profile of each material are given out.

Key words: high power laser effect, ablation load, propagation features of shock-wave in the target
