Purpose of the development: A method for initiating pulsed laser radiation of explosives based on highly sensitive complex and simple salts has been developed.

Recommended application field: Mining industry, machine building.

Technical characteristic: An experimental model of the system with such technical characteristics has been created: - the energy of the laser monopulse is 0.3 mJ; - the pulse duration is 11 ns; - number of channels - 3; - electronic commutation between channels with an error of 1s; - the delay of operation of optical detonators - 10 s; - number of detonators - 500; The distance from the laser to the charges - 500 m. The radiation wavelength is um, = 1.06. Pulse duration <30 ns.

Advantages over analogues: The laser system for initiating explosive charges is safe to use and ensures the precessiousness of the execution of explosive processes. The physical potential of the laser system exceeds the potential of any known BP initiation systems. The created explosive mixtures (VS) exhibit a sensitivity that is 1.5-2 orders of magnitude greater than the lead azide's ability to undermine.

The development stage readiness: Ready for application

Description of the development:
()
A physicomathematical model for the initiation by a laser monopulse (PM) was developed (the radiation wavelength is um, ? = 1.06 pulse duration <30 ns), based on the "hot spot" ideas that arise when light is absorbed by optical microinhomogeneities of BP crystals of size ~ 1 m. It is established that for each BC there is an optimal concentration of transparent binding (20-50%), when the sensitivity of the connection to the action of the laser pulse (LI) is maximal, and to shock mechanical loads - is minimal. An explosive compound BC-7 was developed, which detonates only when exposed to the LI and can only burn under the influence of other factors. The peculiarities of the initiation of the aircraft by narrow laser beams have been established, with the aim of using them in initiation systems using light-conducting networks and the characteristics of the mechanical action of detonation products of thin films from the aircraft on materials. An optical system for initiation of explosive charges (OPSIN) for enterprises of the mining and metallurgical complex was developed. An experimental model of the system was created. Fundamentally new methods of surface hardening of metal structures of complex shape have been developed.
