摘要
利用经典系综理论研究了强超短激光脉冲作用下的（一维）氦原子的非依次电离过程．通过对先后电离的两个电子的平均库仑势能和距核的平均距离的动力学模拟发现：在脉冲长度不变的条件下，长波长和高强度的超短激光脉冲更有助于非依次电离的发生．
Abstract The nonsequential ionization of one dimensional helium atom under an
intense ultrashort laser pulse is investigated with a classical ensemble theory.Through the
dynamic simulation of the average Coulomb potential and the average distance between electron
and nucleus,we found that high intensity and long wavelength favour the occurrence of
nonsequential ionization for a given duration of pulse.
