Light propagation and random lasing — •Andreas Lubatsch and Hans Kroha — Physikalisches Institut, Universitaet Bonn

We present caculations and numerical results for light propagation in disordered media. We consider vector waves passing through a system of randomly distributed Mie - scatterers. The scaterers themselves can consist of optical active media. We present as well results for such systems, which are known as random lasers. In order to find the results, we calculated the necessary transport properties including e.g. the exact Ward Identity and the diffusion constant.
