Abstract: The results of experiments on laser initiation of explosive transformations in energy-saturated composites based on nanoporous silicon have been presented. Calcium perchlorate has been used as an oxidizer. It has been shown that the additive of graphene-like powder material (20–30) wt% in the energy-saturated composite increases its sensitivity to infrared laser radiation and excites rapid exothermic reactions in it.

Keywords: laser radiation, energy-saturated composition, nanoporous silicon, explosive transformations.
