Summary form only given. In laser drilling with short pulses many material phases with very different properties are simultaneously present which complicates the modeling of their interaction with each other. The demonstrated hydrodynamical model is based on a commercial code and uses a continuous description of solid, melt, and vapor by means of an equation of state. It is shown that the resulting ablation dynamics is very sensitive on the choice of the optical properties of the metal vapor. In order to consider the beam propagation within the plasma plume and the drilled hole, a numerical approach for solving directly Maxwell equations on a microscopic scale is presented, additionally.
