Abstract

A model is presented for predicting the temperature rise in an opaque material during the absorption of a moderately short pulse of energy. Experimental verification of the model employing a pulsed ruby laser and a cadmium telluride plate is described. Two distinct damage thresholds were noted: (1) at modest energy levels plastic deformation occurred, and (2) the higher energies resulted in surface melting.
