摘要：

We compare calculated optical harmonic spectra for the hydrogen molecule and the hydrogen atom in an intense, linearly polarized laser field. The hydrogen atom calculations use an exact, time-dependent method and the hydrogen molecule calculations are performed in a time-dependent Hartree-Fock approximation. In both cases, the laser-matter interaction is treated completely non-perturbatively. We show that if the H-2 bond length is stretched so that H-2 has the same ionization potential as H, both systems produced remarkably similar harmonic spectra when irradiated with a 1064 nm laser at 1 x 10(14) or 2 x 10(13) W/cm2.
