摘要
通过数值求解一维含时薛定锷方程，研究了阈上电离与高次谐波随激光强度的变化关系。结果表明，两者具有相同的特性，都具有平台区和截止位置，但两者又有差别。较低激光强度作用下，谐波谱有平台而光电子能谱为单调下降的，激光强度较高时，两者都有平台。
By solving the 1 dimensional time dependent Schrodinger equation, the above threshold ionization (ATI) and high order harmonic generation (HOHG) of atom under different laser intensity are obtained, and the relation between the ATI and HOHG is discussed. The results show that under higher laser intensity, both the ATI and HOHG have plateau and cutoff, but under lower laser intensity, the HOHG has plateau and the ATI decreases monotonically.
