强激光加载真空中铝靶冲量耦合的数值模拟
Numerical simulation of impulse coupling to aluminum in laser ablation in vacuum
摘要
Abstract
In order to obtain the mechanical coupling coefficients, a 1-D bulk absorption model to simulate the solid target ablated directly by the laser beam was presented, numerical calculation of impulse acting on the target in vacuum with different laser parameters was performed with fluid dynamics theory and 1-D Lagrange finite difference scheme. The calculated results of the impulse coupling coefficients are in good agreement with the experimental results and Phipps empirical value. The simulated results show that the mechanical coupling coefficients decrease with the increment of laser intensity when the laser pulses generate plasma.关键词
