Abstract
We develop a numerical scheme to investigate the high-order harmonic generation (HHG) in intense laser-matter interactions. We represent the time-dependent wave function in the basis of the eigenstates of the field-free Hamiltonian and trace its temporal evolution. Our full quantum simulations reveal that continuum electrons with a broad energy distribution contribute equally to one harmonic and the excited state also plays an important role in the molecular HHG. These results imply a laser-intensity-dependent picture of intramolecular interference in the HHG.
