LASER INITIATION DEVICE Russian patent published in 2019 - IPC F42B3/113 F42C19/08 H01S3/23 H01S5/40 

FIELD: unified pyrotechnic device initiation systems.

SUBSTANCE: invention relates to semiconductor lasers, particularly to design of optical transmitting modules with fiber output, and can be used in laser systems for initiation of pyrotechnic devices of automation and explosives. Laser initiation device includes a housing, in which laser emitters, lenses and gradient lenses, and optical fiber are coaxially located. Device is equipped with an electric motor, on the shaft of which a drum is fixed with the possibility of rotation, along the perimeter of which the light filters are evenly arranged, and cartridges fixed uniformly on the end surface of the housing on the circumference. Each cartridge case has a groove for light filters and a gradient lens, an additional gradient lens, a lens and a laser emitter are arranged in series from the end surface of the housing, the light filter groove is made between the gradient lenses.

EFFECT: enabling controlled breakage of the optical circuit, control of energy parameters and integrity of the fiber-optic channel.
