Optical Properties of Clusters — •Thomas Raitza, Heidi Reinholz, and Gerd Röpke — Universität Rostock

The measurements of optical properties are relevant for plasma diagnostics. The investigation of reflectivity and absorption of electromagnetic waves in inhomogeneous media will be done with special attention to laser excited clusters. Interactions of cluster systems with intense laser pulses were investigated via MD simulation.

Via MD simulation the current auto correlation function (ACF) was calculated. Optical properties derived from current ACF will be presented. The cluster size dependence of the optical properties will be discussed as well as thermodynamic relations and the influence of the laser field.
