摘要
随着阿秒激光的出现,人们可以深入原子内部研究大约100as时间尺度内电子的运动,这为研究阿秒时间分辨率下电子与离子碰撞,高次谐波产生等物理过程提供了机会。目前,在实验方面正致力于研究如何产生更短的阿秒激光脉冲,理论上则注重对多电子电离和高次谐波产生等物理过程进行拟合。
The motion of the electron in an atom within about 100 as resolution can not be studied until the appearance of attosecond laser. This provides a chance for the study of high harmonic generation and recollision between electrons and ions within attosecond resolution. Now, great effort has been put into producing much shorter attosecond pulses in experiment, simulating the processes of multi-electron ionization and high harmonic generation(HHG) in the theory.
