Controlling the dissociation of an HD$^{+}$ beam with intense two-color laser field

ORAL

Abstract

Electron localization on a specific nucleus during strong-field dissociation of a molecular-ion is controlled by the relative phase between the 790 and 395 nm components of a linearly-polarized ultrashort laser pulse. We have observed both spatial and channel asymmetries experimentally for an HD$^{+}$ target. The spatial asymmetry, which has been observed before, has been understood as being due to the breaking of the spatial symmetry of the driving field. The channel asymmetry, namely the controlled dissociation into either H$^{+}$+D(1s) or H(1s)+D$^{+}$, is independent of the spatial asymmetry and is not as easily understood in the language of driving field asymmetry. We will discuss these first measurements of this effect as well as an attempt to understand both the spatial and channel asymmetries within a single, unified picture.
