摘要: 采用量纲分析方法,解析地描述了脉冲强激光产生等离子体的流体动力学状态,根据密度特征把等离子体划分成不同的区域,并推导出了激光等离子体参量与激光参数以及靶材参数的定标关系,和有关结果比较符合得较好.Abstract: By means of dimensional analysis,the hydrodynamic states of lase-rinduced plasma were described.According to the intensity distribution,the lase rinduced plasma can be separated into several regions,and the every parameters of plasma,laser and target materials can be derived to demonstrate a set of scale formulas.This result achieved the theoretical base for rapidly calculate the laser induced plasma parameters.
