Abstract

Self-focusing of TEA-CO2 laser radiation seems to be a plausible explanation for the superunity values of the ratio between the vapour - and plasma- transmitted energy density and the incident energy density, that are evidenced by observations at copper targets' irradiation. The experimental results, which are described in comparison with those obtained for aluminium targets, are discussed in terms of the predictions of the main physical mechanisms involved in self-focusing initiation.
