“弹弓”laser驱动的等离子体电子加速机制

A "slingshot" laser-driven acceleration mechanism of plasma electrons

Gaetano Fiore, Sergio De Nicola

摘要:

我们简要报告最近提出的[G。菲奥雷河费代尔大学等离子体21(2014),113105],[G. Fiore,S. De Nicola,arXiv:1509.04656]电子加速机制称为“弹弓效应”:在适当的条件下,超短超强激光脉冲撞击低密度等离子体表面,预期会导致表面高能电子束沿与脉冲传播方向相反的方向被驱逐;这是由于巨大的有质动力、由电荷分离产生的巨大纵向场以及激光光斑的有限尺寸的相互作用。

英文摘要:

We briefly report on the recently proposed [G. Fiore, R. Fedele, U. de Angelis, Phys. Plasmas 21 (2014), 113105], [G. Fiore, S. De Nicola, arXiv:1509.04656] electron acceleration mechanism named "slingshot effect": under suitable conditions the impact of an ultra-short and ultra-intense laser pulse against the surface of a low-density plasma is expected to cause the expulsion of a bunch of superficial electrons with high energy in the direction opposite to that of the pulse propagation; this is due to the interplay of the huge ponderomotive force, huge longitudinal field arising from charge separation, and the finite size of the laser spot.
