摘要
在文献[18]的基础上进一步讨论真实脉冲激光作用下的原子超阈值离化,在考虑了初始离化时刻的影响后,结果清楚地表明,随激光脉宽减小而产生峰红移,以及同时出现的离化电子谱峰的增宽现象.
Based on the results in previous paper, we further discussed the above-threshold lonzation (ATI) of atom under intnse laser field with realistic pulse shape. Affter considering the influence of initical ionization time, it is more clear that the red shift and brodening of ATI peaks appear as the laser pulse width changes from long to short regime.
