Abstract

We perform an experimental study on comparison between the ionization of homonuclear diatomic molecules (O2 and N2) and their companion atoms (Xe and Ar) radiated by circularly polarized intense laser fields. We find that the ionization of O2 shows suppression with respect to its companion atom Xe, which exhibits a clear wavelength and intensity dependence similar to that in linearly polarized laser field, while the ionization of N2 behaves like its companion atom Ar. With the help of S-matrix theoretical analysis, our observations can be attributed to both the molecular orbital and the two-center interference effect in molecular ionization process.
