Abstract:
The threshold pulsed laser energy for initiating the explosive decomposition of silver azide single crystals was studied experimentally for various diameters of the irradiated area. It was found that, as the diameter of the irradiated area was decreased from 1000 to 10 $\mu$m, the threshold energy density of explosion initiation increased by more than an order of magnitude. It is shown that this dependence cannot be explained by light scatter, diffusion of reactants, or heat transfer from the reaction zone.
Keywords:heavy metal azides, pulsed laser radiation, explosive decomposition, initiation criteria, transfer of chemical reaction energy.
