N2 - We experimentally investigate high-order-harmonic generation (HHG) of diatomic molecules (O2, N2) and their companion atoms (Xe, Ar, respectively, which are of nearly the same ionization potentials as the corresponding molecules) with midinfrared femtosecond laser pulses. It is found that the cutoff of O2 extends to higher energy as compared to that of Xe, and the extension of cutoff energy of O2 depends on the driver wavelength. Our theoretical analysis shows that the ionization suppression induced by two-center interference should be responsible for the harmonic cutoff extension of O2.
