Paper Abstract

In the present work we discuss in some details the development of the stress induced into the target by laser ablation in air. The analytical treatment based on the variable energy blast theory allowed to provide the scaling law of the peak and the temporal profile of the generated pressure wave. Measurements of the acoustic transient associated with excimer laser ablation of polyimide, obtained by means of polyvinyldenefloride (PVDF) sensors were successfully compared with the behaviors provided by the analysis. The description here proposed can be extended to pulsed laser ablation of soft tissues where the target material is removed in vapor or gaseous phases.
