Theory of Spectroscopy and Dynamics in Laser-Irradiated Adspecies-Surface Systems.
Abstract
Recent progress in the theory of spectroscopy and in dynamics laser irradiated adspecies surface systems is discussed. This article is divided into three main sections. First, a first principles approach for describing vibrational excitation and relaxation of a laser excited adatom is presented. A tractable approximation is introduced in order to numerically deal with the long time behavior of the dynamics. In the next section, surface dressed optial Bloch equations are solved for the resonance fluorescence spectrum of a laser driven two level atom near a flat metal surface and also near a rough metal surface modeled by a hemispheroid on a perfectly conducting plane. In the final section, the problem of laser induced period chemical vapor deposition is addressed, and a theoretical analysis of selected aspects of an experiment on the deposition of cadmium onto a silica surface is carried out, where the cadmium is produced by laser-induced dissociation of dimethyl cadmium gas above the surface.
