用强场近似方法研究强激光场中H原子的电离
Study on ionization of H atoms by intense laser fields with strong-field approximation method
摘要
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 Schr(o)dinger 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 Schr(o)dinger equation at longer laser wavelength.关键词
