Abstract
The formation of a deposit from mixture of PETN with fine-dispersed aluminum under the action of neodymium laser radiation in a free generation mode is studied. This paper also describes the efficiency of a deposit as a means to reduce the energy of laser initiation of mixtures as a function of PETN dispersion, aluminum content in the initiated mixtures and the deposit, mixture density, and diameter of the region of laser action on the explosive. The compositions of the mixtures for preparation of deposits optimal in composition, which reduce the initiation energy of the mixtures of PETN with aluminum up to 3.75 times, are determined. The mechanism of functioning of the deposit during laser initiation of the mixtures of PETN and aluminum is discussed.
