laser脉冲对等离子体通道尾流场的激发

Excitation of wakefields in a plasma channel by a laser pulse

R. Annou, V. K. Tripathi

摘要:

本文研究了在阶跃密度分布等离子体通道中三角形脉冲激发尾流场的解析解,得到了精确解。激励对于t~tp更有效,其中t是脉冲的上升时间,tp是等离子体周期,尽管它对于t~20 tp仍然是显著的。在前一种情况下,尾流势是有质动力势的1.7倍,而对于后者,尾流势下降到有质动力势的1.4倍。

英文摘要:

The excitation of wakefields by a triangular temporal profile laser pulse with an abrupt fall in a step density profile plasma channel is investigated analytically and an exact solution is obtained. The excitation is more efficient for t~tp, where t is the rise time of the pulse and tp is the plasma period, though it is still significant for t~20 tp. The wake potential in the former case is 1.7 times the ponderomotive potential, whereas it falls to 1.4 times the ponderomotive potential for the latter.
