LASER INITIATION MEANS Russian patent published in 2016 - IPC F42B3/113 

FIELD: blasting.

SUBSTANCE: invention relates to laser initiation means manufactured with use of secondary explosives. Laser initiation means includes a set coaxially installed in body 1 radiation source 2, explosive charge, optical support 3 disposed between radiation source 2 and explosive charge, gradient optical lens 4 disposed between radiation source 2 and optical support 3 made of optically transparent ceramics. Explosive charge is configured in form of batches of initiator 5 and outlet 6, thus initiating linkage 5 is in form of a thin high density superfine charge of a secondary explosive and is located between optical support 3 and output linkage 6, and output linkage 6 is made of a secondary explosive or pyrotechnic composition.

EFFECT: higher efficiency, faster operation and reliability of laser initiation means.
