摘要

The above-threshold ionization (ATI) spectra of H-atom in intense laser fields (laser intensity I is up to 1018W/cm2)are calculated. It is found that the kinetic energy of the ejected electron at the location of the peak of the ATI spectra is about equal to the corresponding ponderomotive potential of the applied laser fields. This result is consistent with that obtained by Wilks et al. and fits the experimental results of the super thermal electron. A possible new mechanism of the super thermal electron generation is proposed.
