Paper Abstract

We propose an original approach to describe the transient behaviour of experimental optical coupling parameters of materials, i.e. absorptivity, reflectivity, ... at frequency w, versus time t. This analysis, based on the distribution theory and Laplace transforma-tion, extends and generalizes the classical definition of stationnary parameters, including temporal variations of surface temperature. It provides a method to deduce characteristic coefficients of laser-material interaction from experimental data on reflected and transmitted laser beams. At last, this method presents advantage of using simple rules of operational calculus as developped for electronic applications.
