PHYSICAL MODEL ABOUT LASER IMPACT ON METALS AND ALLOYS

Abstract

In this article we present our physical model for interaction of laser radiation with metals and alloys through structural changes, melting and vaporizing. We describe the interaction of laser radiation with materials, kinetic process of energy transmitting from free electrons to the crystal lattice and propagation of heat and the processing zone. We consider influence of optical and thermal properties over exploring process as they change with temperature and in the presence of mixtures.
