Thermoelastic Response to a Short Laser Pulse.

Abstract

The authors consider a one-dimensional model of the thermoelastic response to laser heating by a pulse of very short duration. They treat the linear equations of thermoelasticity by perturbation methods using the pulse duration as the perturbation parameter. The perturbation analysis separates the problem into two time regimes, the short time scale, which is of the same order as the pulse duration, and the long time scale, which is much longer than the pulse duration. Convenient analytical expressions are obtained for the temperature change and displacement in both time regimes.
