摘要
模拟研究了自由电子在超强激光场中的动力学特性,发现当场强高达Q=eE/mecω100时,电子动力学行为将出现全新的现象,其特征为描写激光束的有质动力势模型已完全不再适用,能量较低的电子有可能进入强场区,被光束所俘获,并被剧烈地加速.详细地讨论了这一俘获与加速的规律,指出这一新现象对发展远场激光加速器的意义.
Abstract Electron
dynamics in the extra intense stationary laser field has been investigated by numerical simulation
method.It is found,for the first time to our knowledge,that when Q 100( Q=eE/m e cω ,is a
dimensionless parameter measuring the field intenstiy),the electron with relatively lower energy
can be captured and violently accelerated by the laser beam.This is a new phenmenon which is of
potential importance to the far field laser acceleration in vacuum.
