Using a kinematically complete XUV-pump IR-probe experiment, we have studied the dissociation dynamics of molecular hydrogen induced by ultra-short extreme-ultraviolet (XUV) and near-infrared (IR) laser pulses by varying the time delay between these pulses. The measured fragment velocities are time-delay dependent, showing that the reaction kinematics can be controlled by varying the retardation of the control pulse. A semi-classical model, supported by a quantum dynamics simulation, provides an intuitive understanding of the underlying mechanism in terms of particle motion on laser-induced potential energy surfaces.
