KW - time-dependent density functional, high-order harmonic generation, attosecond.
AB - <p style="text-align: justify;">The ionization and high-order harmonic generation (HHG) of a hydrogen molecule in an ultra-short
intense laser are investigated by using the time-dependent density functional theory (TDDFT). Our numerical
results show, the higher ionization probability and lower cutoff energy of harmonic emission compared with
those from the time-dependent Schrodinger equation (TDSE), which is caused by the smaller ionization
energy from TDDFT. The disparities of the HHG transient behavior and the attosecond pulse are also
discussed.</p>
