Abstract
Low conductivity, laser-irradiated thin films such as the chalcogenides employed for optical data storage can display manifestations of signific ant through-thickness thermal gradients. A combined Laplace-transform, Fourier-integral method was utilized to derive the temperature distributions in laser-irradiated, low conductivity thin films, and the results were used to examine the effects of some marking parameters on through-thickness thermal gradients. These were found to be strongly influenced by the laser incidence direction, the coefficient of optical absorption, and the film thickness, and influe:aced to a somewhat lesser degree by the scanning velocity.
