Ultrafast laser control of electron dynamics in atoms, molecules and solids

Abstract

Exploiting coherence properties of laser light together with quantum mechanical matter interferences in order to steer a chemical reaction into a pre-defined target channel is the basis of coherent control. The increasing availability of laser sources operating on the time scale of molecular dynamics, i.e. the femtosecond regime, and the increasing capabilities of shaping light in terms of amplitude, phase and polarization also on the time scale of molecular dynamics brought the temporal aspect of this field to the fore. Since the last Faraday Discussion (Faraday Discussion 113, Stereochemistry and control in molecular reaction dynamics) devoted to this topic more than a decade ago a tremendous cross-fertilization to neighbouring “quantum technology disciplines” in terms of experimental techniques and theoretical developments has occurred. Examples are NMR, quantum information, ultracold molecules, nonlinear spectroscopy and microscopy and extreme nonlinear optics including attosecond-science. As pointed out by the organizers, this meeting brings us back to chemistry and aims to assess recent progress in our general understanding of coherence and control in chemistry and to define new avenues for the future. To that end we will in the Introductory lecture first shortly review some aspects of coherent control. This will not be fully comprehensive and is mainly meant to give some background to current experimental efforts of our research group in controlling (coherent) electronic excitations with tailored light fields. Examples and perspectives for the latter will be given.
