摘要
本文通过建立一个超强超短激光脉冲与低密度等离子体相互作用的简单模型,讨论了相互作用过程中的快电子流聚束现象,得到了产生快电子流聚束的条件以及快电子流聚束后的半径所满足的关系.
In this paper, a simple model is proposed for the interaction of ultra-short and ultra-intense laser pulses with underdense plasma. The self-focusing of fast electrons flow is discussed;the condition for the fast electrons self-focusing to occnr,and the radius of the fast electrons beam after self-focusing is obtained.
