Abstract  Numerical simulations of ionization and dissociation processes of hydrogen molecular ion H2+ interacting with two-color intense ( 1014W/cm2-1015W/cm2) ultrashort (the duration ≈ 22fs) laser pulse are made. The result shows that the ionization and dissociation processes are strongly dependent upon the relative phase between the two color fields. It means that, in the case of ultrashort pulse, the phase coherence control of ionization and dissociation processes can be realized.
