DETERMINATION OF THE EFFECTIVE COEFFICIENT OF ABSORPTION IN LASER HEATING

Abstract

Models for describing thermomechanical processes during laser irradiation of deformable solids are proposed. Energy parameters play the main role in the action of OCG (optical quantum generators) on solids. The specific power (energy structure of the pulse) of laser radiation can be roughly represented as the product of two functions, one of which most often has the shape of a rectangle or triangle (time evolution), the other has a normal shape (Gaussian distribution). An important aspect of modeling the processes of impact of CPE (concentrated energy flows) on solid bodies is the adequacy of the effective absorption coefficient during laser heating.
