Abstract
A technique is described of obtaining directly the energy absorption profile of a solid heated by pulses of intense radiation. The appropriate thermoelastic equations were solved for two cases of particular interest, instantaneous deposition and energy absorbed at a constant rate. The dynamic response of aluminum and copper to electrons of everage energy 1.5 MeV was measured by means of a laser interferometer, and the resulting energy profiles were compared with profiles obtained using a thin film dosimetry technique. The resulting quantitative agreement with the thermoelastic theory is discussed.Keywords
