摘要
激光在等离子体中传播时形成的自生通道、成丝已被实验所观察,由于激光与等离子体相互作用时各种非线性效应十分复杂,通道形成的机理还存在争议,本文主要介绍目前等离子通道形成的几种模式及一些重要实验结果,并提出一种新的通道形成的机制。
Self- generated channeling and filamentation during the propagation of laser in plasma have been observed in experiment. The formation of plasma channel have been still discussed due to complex nonlinear effect in channel. In this paper we present some kinds of model about formation of channel and some important experiment results and propose one new mechanism.
