A method for the generation of a single short duration stress pulse in a solid is described briefly in this report. A giant laser pulse of 10 to 20 nanosecond duration is used to heat a layer of liquid on top of the solid. The heating occurs at constant volume, producing a pressure which is relieved by a wave propagating through the liquid layer. A 0.2 microsecond pulse is produced when a 0.25 mm layer of ethyl alcohol is used.
