飞秒激光脉冲对目标的机械作用可能会导致受照射前层的烧蚀以及目标后侧的剥落。通过使用两个 EAM 势（我们和 Mishin 等人）和我们的并行自动平衡 MPD3 代码进行分子动力学 (MD) 模拟，研究了激光加热后固体铝膜的膨胀动力学。结果发现，后侧散裂阈值又是前侧剥落阈值的一半。实验和评估的特性在凹坑深度和烧蚀阈值的入射注量方面都非常吻合。
The mechanical action of femtosecond laser pulse on a target may result in ablation of the irradiated frontal layer and spallation of the target rear side as well. The dynamics of expansion of the solid Al film after laser heating is studied by means of molecular dynamics (MD) simulations with the two EAM potentials (ours and Mishin et al.) and our parallel auto-balancing MPD3 code. It is found that the rear side spallation threshold is half as much again the frontal ablation threshold. The experimental and evaluated characteristics agree well in both crater depth and incident fluence on the ablation threshold.
