中文摘要	the ionization rate of molecules in intense laser fields may be much lower than that of atoms with similar binding energy. this phenomenon is termed the ionization suppression of molecules and is caused by the molecular inner structure. in this paper, we perform a comprehensive study of the ionization suppression of homonuclear diatomic molecules in intense laser fields of linear and circular polarizations. we find that for linear polarization the total ionization rate and the ionization suppression depend greatly on the molecular alignment, and that for circular polarization the ionization suppression of molecules in the antibonding (bonding) shells disappears (appears) for laser intensities around 10(15) w/cm(2). we also find that the molecular photoelectron energy spectra are greatly changed by the interference effect, even though the total ionization rate of molecules remains almost the same as that of their companion atoms.
