Abstract

To describe transient behaviour of experimental laser-material optical coupling, i.e. absorptivity, reflectivity, ..., we propose an original approach based on the distributions theory and Laplace transformation. It allows extent and generalization of the classical definition of stationary parameters to any temporal situation of incident laser beam, including temporal variations of temperature, pressure and surface transformations. Using simple rules of operational calculus as developed for electronic applications, it provides a method for evaluation of the part of laser energy actually absorbed by the material versus time.
