Modify the dynamic process of the bulk target's plasma plume generated by pulsed laser

  • 摘要: 利用质量连续性、动量守恒和能量守恒这三个基本方程，研究高能脉冲激光照射块状靶材产生等离子体的物理特性。采用差分法和Pichard迭代法，求解带特定边界条件的流体力学三方程，得出已喷射等离子体的温度、密度和速度的分布的迭代方程，并用计算机进行了数值模拟。
    Abstract: The plasma characteristics of the bulk target irradiated by pulse laser is studied in detail, and the theoretical model of pulsed-laser-driven ablation is set up accordingly. In addition, the velocity distribution of the plasma is discussed. Moreover, the plasma density and temperature near the ablating surface as the function of time are discussed respectively by using hydrodynamic theory and the heat conduction equation .At the same time, our theoretical results are compared with our experiments and other authors' conclusions.
