Abstract :
Summary form only given. During the past few years a great deal of attention has been focused on the development of photothermal methods in order to characterize the thermal properties of solid samples. In this work the harmonic local surface deformation induced by a Gaussian pump laser beam modulated in time is studied through the photothermal method by the direction change of a second laser beam (probe) reflected by the bended surface.
