Abstract
A simple model for reactive gas laser cutting is presented. A thin metallic film under laser irradiation in an oxidizing atmosphere is considered. The stability of the diffusion-controlled growth of an oxide layer with external cooling of the system is investigated in terms of nonlinear point-system dynamics. Depending on the material and input parameters the system can exhibit limit cycles. Instabilities of this kind can be sources for striations on the cutting surface.
