Comparison of dissociative ionization of H₂, N₂, Ar₂, and CO by elliptically polarized two-color pulses

We study the directional dissociative ionization of diatomic molecules (H₂, N₂, Ar₂, and CO) by intense phase-controlled elliptically polarized two-color pulses. The phase between the two colors of our elliptically polarized two-color pulse is unambiguously and straightforwardly assigned by tracing the momentum of the released electron, streaked by the rotating laser field, which is imprinted in the momentum of the correlated ion. The laser-driven electron motion, electron-localization-assisted enhanced multielectron ionization, and role of the orbital shape for the asymmetric dissociative ionizations of various molecules are discussed.
