Abstract:
Results of studying optoacoustic characteristics of pentaerythritol tetranitrate (PETN) specimens with inclusions of ultrafine aluminum particles ($100$ nm) are presented. Regularities of the increase of extinction coefficient $k_{\mathrm{ef}}$ and signal amplitude $U$ on a piezodetector by increasing laser-pulse fluence $H$ have been established. Estimates have been made, and it has been concluded that, during a laser pulse, heating of aluminum inclusions and a shell surrounding it occurs up to a gasification temperature and appear craters on a specimen's surface appear at $H>0.1$ J/cm$^2$.
