| 摘 要： | 利用传统的强场近似方法和考虑Coulomb修正的强场近似方法，计算了H原子在激光场中的总电离几率及H原子在不同波长激光场中电离的能量谱，并将得到的能量谱与直接数值求解含时Schrödinger方程的结果进行了比较，结果发现：当激光波长较长时，考虑Coulomb 修正的强场近似方法得到的结果与数值求解含时Schrödinger方程的结果符合得较好。

| Abstract: | The total ionization probability and the ionization energy spectra of hydrogen atom in the linear polarization laser fields of different wavelength are investigated with the approach of traditional SFA and SFA with Coulomb correction. Compared the energy spectra with those of direct numerical solution of time-dependent Schrödinger equation, it is shown that the results of SFA with Coulomb correction are in good agreement with those of direct numerical solution of time-dependent Schrödinger equation at longer laser wavelength . |
