Laser pulse control of molecular dynamics: Consideration of some experimental constrains — •Tomáš Mančal and Volkhard May — Institut für Physik, Humboldt-Universität zu Berlin, Hausvogteiplatz 5-7, 10117 Berlin

Optimal Control Theory (OCT) became the prevailing method to study laser pulse control of molecular dynamics. The contribution addresses some of the obstacles remaining to apply this method to concrete systems and to predict the outcome of recent control experiments. The problems are not caused by peculiarities of the molecular structure but are related to experimental conditions such as (a) the influence of a thermal environment (b) the action of disorder (molecular dipole orientation) and (c) the problem of time non-local measurement (such as pump-probe) The general OCT including these phenomena is formulated and applied to a study of optical control scenarios for a certain class of molecular systems varying from a simple diatomic molecule to a polyatomic system showing ultrafast electron transfer. Resulting optimal fields are mapped on those feasible by a Liquid-Crystal Spatial Light Modulator in order to check for their experimental relevance and feasibility with recent technique.
