摘要 引入非线性空间变换,用伪谱方法求解了一维原子在强激光场中的薛定谔方程,计算了一维原子在强激光场中的高次谐波和电离几率,其结果与分裂算符法得到的结果符合得很好. The t ime-depe ndent Shrdinger equation of o ne-dim ensional atom in intense laser field with pseudospectral method is solved by introducing nonlinear space transformation,and the high order harmonic generation and ionization probability are calculated for one-dime nsional atom in intense laser field.The results have good agreement with those of sp lit-ope rator method.
