利用Coulomb—Volkov方法研究了H原子在不同波长的线性极化强激光场中电离的能量谱和动量谱,并与强场近似和直接数值求解含时Schrodinger方程的结果进行比较,结果发现:随着激光频率的增加,由Coulomb-Volkov方法得到的结果与数值求解含时Schrodinger方程的结果符合得很好.
The energy spectra and momentum spectra of hydrogen atom in the linear polarization laser fields of different wavelength are investigated with Coulomb-Volkov approach. Compared the results with the ones of strong-field approximation and direct numerical solution of time-dependent Schrodinger equation, it is shown that the results of the Coulomb-Volkov approach are in good agreement with direct numerical solution of time-dependent Schrodinger equation with higher frequency of laser fields.
