Abstract

FIELD: pyrotechnics, for example, blasting devices and pyrotechnical charges actuated by electromagnetic radiation. SUBSTANCE: the offered pyrotechnics uses a pyrotechnical charge with an optical fuse-initiator connected to a pulsed light source through a light conduit; the light conduit is made of fibre with the core of alloyed laser glass, and bent in the form of a loop so that the end faces of the fibrous light conduit are positioned in the optical fuse-initiator, and the middle part of the fibrous light conduit is placed near the pulsed light source. In a particular case the light conduit is made of a bundle of fibres with the core of alloyed laser glass. EFFECT: enhanced reliability and safety of pyrotechnics operation.

Claims (1)

The technical proposal relates to the field of pyrotechnics, for example, to explosive devices and pyrotechnic charges triggered by electromagnetic radiation. The purpose of the proposed technical solution is to increase the reliability and safety of the pyrotechnic device. In the proposed pyrotechnic device containing a pyrotechnic charge with an optical initiator fuse connected to a pulsed light source through a light guide, the light guide is made of fiber with a core of doped laser glass and is bent in a loop so that the ends of the fiber light guide are placed in the optical initiator fuse, and the middle part of the fiber is located near the pulsed light source. In the particular case of the implementation of the pyrotechnic device, the fiber is made of a bundle of fibers with a core of doped laser glass.
