The aim of this work is to calculate the regularities of the explosion decomposition of the composites of pentaerythritol tetranitrate and gold initiated by the laser pulse of 12 ns's duration. In the range of nanoparticles' radii from 20 nm to 120 nm the maximum values of the critical initiation energy density, for which the explosion is not realized, were calculated. It was shown that the nanoparticles, whose radii are 60 nm are the optimal ones for this pulse duration and provide the lowest
