  • Optopyrotechnic initiator
    Patent number: 9970737
    Abstract: An optical initiator of a pyrotechnic charge, including: a body including a cavity, which contains the pyrotechnic charge and a mechanism for igniting the charge by absorption of a laser radiation, the ignition mechanism being placed in contact with the charge; a laser radiation source; an optical fiber for transporting laser radiation from the source to the ignition mechanism. The ignition mechanism includes a metal plate and the metal plate and the laser radiation source are configured for a laser radiation issuing from the laser radiation source to be absorbed by the metal plate and converted into thermal energy, so that thermal conduction of the thermal energy from the metal plate to the pyrotechnic charge causes the ignition of the pyrotechnic charge. The metal plate can include perforations arranged periodically.
