Abstract
We investigate the effect of the interference minima of the high-order harmonic generation (HHG) in H2+ molecule with varying the full width at half maximum (FWHM) of the laser field by solving the one-dimensional (1D) time-dependent Schrödinger equation (TDSE) within the non-Born-Oppenheimer approximation. The numerical results show that the probability of the electron recombined with the two nuclei is different with the variation of the FWHM. The HHG spectrum of H2+ molecule is separated into two parts according to the electronic coordinate z (z>0 and z<0), which illustrate the contributions of the two nuclei to the harmonic generation. In addition, we investigate the time-evolution electron wave packet distributions to illustrate the underlying physical mechanism.
