    Abstract
    Two-color (800 and 400 nm) short (45 fs) linearly polarized pulses are used to ionize and dissociate D2 into a neutral deuterium atom and a deuteron. The yields and energies of the ions are measured left and right along the polarization vector. As the relative phase of the two colors is varied, strong yield asymmetries are found in the ion-energy regions traditionally identi?ed as bond softening, above-threshold dissociation and rescattering. The asymmetries in these regions are quite different. A model based on the dynamic coupling by the laser ?eld of the gerade and ungerade states in the molecular ion accounts for many ...

As the relative phase of the two colors is varied, strong yield asymmetries are found in the ion-energy regions traditionally identi?ed as bond softening, above-threshold dissociation and rescattering. The asymmetries in these regions are quite different. A model based on the dynamic coupling by the laser ?eld of the gerade and ungerade states in the molecular ion accounts for many of the observed features.
