Laser initiators perform the same roles as conventional initiators although they use an alternate activation method – infrared laser light. The initiator output can be catered to either favor sustained pressure for performing mechanical work, or to emphasize hot particles for igniting adjacent energetics. Laser initiated devices offer unique characteristics over electrically ignited devices. They are ESD, RF and EMI/EMP immune which can be advantageous in certain design applications. They also generally present a system weight reduction for cabling because the fiber optic lines weigh less than typical copper lines and energetic transfer lines. We have qualified designs which utilize 100, 200 and 400 micron fiber optic cable assemblies. Any of the current designs can be adapted to other specified fiber optic systems.
Reliability and safety have been demonstrated on these designs as attested by the approval of range safety and man rated system uses.

Laser initiators can be used in applications requiring pressure, hot particles, or both to activate further events and systems. The output pressure is useful for driving pistons that perform duties such as pressure vessel nipple removal, puncturing burst disks, activating separation bolts, driving pins forward or channeling the gas to a piston’s far side to retract the shaft (“pin puller” application). For variants emphasizing hot particles, the output may be used to ignite further energetics such as propellants, boosters, time delays, etc.
