摘要: 简要描述了激光在等离子体中传播的三维光路方程的追踪解法,同时对电子热传导中的热流以及非平衡束缚电子占据概率速率方程组给出了一种简便解法.应用这些方法和新近发展的LARED H程序,对激光辐照金(Au)圆盘和圆环靶进行了二维模拟,给出了靶等离子体的合理的二维行为特征.

Abstract: A three-dimensional ray-tracing method for laser propagation in plasma and an algorithm of heat flow for electronic conduction are briefly described.A convenient calculation scheme for solving the non-equilibrium Pn equations is also presented.By using these methods and the newly developed LARED-H code,the two-dimensional simulations for the laser-irradiated gold disk and ring target are preformed.The reasonable two-dimensional behaviors of the target plasma are obtained.

Key words: three-dimensional ray-tracing, limited flow heat-conduction, two-dimensional simulation of disk and ring target
