Laser cutting has reached a high degree of industrial maturity.Nevertheless to extend the present range of industrial applications, the performance and quality of laser cutting must be improved.Such improvements can only be achieved if the physical mechanism of laser cutting is deeply understood.Special attention has to be payed to dynamic effects, since they are most important for cut quality.Examples for dynamic effects are the formation of periodic striations, that cause a certain roughness or pulsed operation, that allows cutting of parts with changing curvature without overheating/18/. In the following bulk of the paper, a mathematical analysis of reactive gas assisted laser cutting including dynamic effects is presented. Although that work has partly been published before, the present paper contains an important task, that has never been published before, namely the calculation of the reactive energy gain.
