Using the small parameter method, a numerical solution is found for the nonlinear thermal conductivity equation describing evolution of the temperature field in an absorber after completion of a radiation pulse. High speed (∼106 K/sec) heating of the surface layers over ∼1·10-5 sec is observed. Absorber cooling parameters are obtained as a function of time and distance from the irradiated surface.
