When safety and accuracy are mission critical.

How Laser Detonators Work

Laser detonators perform the same roles as conventional detonators, although they use an alternate activation method – infrared laser light. Laser initiated devices offer unique characteristics Laser Detonator iiover 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. PacSci EMC has qualified designs which utilize 100, 200 and 400 micron fiber optic cable assemblies and our patented Dual Fiber approach to support Optical BIT. Any of the current designs can be adapted to other specified fiber optic systems while supporting redundant initiation.

Reliability and safety have been demonstrated on these designs as attested by the approval of range safety and man rated system uses plus qualification to MIL-DTL-23659.

Our laser detonator designs use either primaries to generation the detonation event or all approved secondaries and approved pyrotechnic material in a run-up design. Thus it is possible to provide a MIL qualified Laser Detonator design which is completely primary free.

FUNCTIONS

Laser detonators can be used in applications requiring shock or severe mechanical impulse to operate. The detonation output is useful for setting off adjacent high order energetics, including transfer lines, or for rupturing adjacent surfaces for various purposes such as releasing pressure or intentionally inducing structural failure mechanisms (e.g. bulkhead or pressure vessel breaching, shape charge activation, etc.).

APPLICATIONS

PacSci EMC laser detonators are qualified and used in missile interceptor applications, flight termination systems, and cockpit egress systems to name a few.
