英文摘要	Using the Lewenstein model combined with the molecular Ammosov-Delone-Krainov ionization theory, laser induced harmonics generated from aligned N-2 molecules are calculated. We focus attention on shifts in minima of the harmonic spectra due to interference between harmonics generated from different molecular orbitals (MOs). When harmonic spectra generated from different MOs are of the same intensity (i.e., the "cross" region of the harmonic spectra), interference is most pronounced. We find that contributions to the harmonic spectrum from different MOs respond differently to the change of the laser intensity. This difference in response results in two phenomena. On the one hand, by changing the laser intensity, harmonics generated from an individual MO may become. more or less prominent, thus, structure-induced minima can appear. On the other hand, when the laser intensity increases, the "cross" region shifts, and multiple-orbital-interference-induced minima appear at different energies.
