| Abstract: | 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. |
