A model providing an accurate estimate of the charge accumulation on the surface of a metallic target irradiated by a high-intensity laser pulse of fs-ps duration is proposed. The model is confirmed by detailed comparisons with specially designed experiments. Such a model is useful for understanding the electromagnetic pulse emission and the quasistatic magnetic field generation in laser-plasma interaction experiments.
提出了一个模型,该模型能够准确估计在持续时间为飞秒至皮秒的高强度激光脉冲辐照下金属靶表面的电荷积累。通过与专门设计的实验进行详细比较,证实了该模型。这样的模型对于理解激光 - 等离子体相互作用实验中的电磁脉冲发射和准静态磁场产生是有用的。
