Abstract

A complete packaged optical firing system was designed and fabricated to be used to trigger optical detonators. The system consists of a specially designed Nd:YAG laser operating at 1064 nm, attenuator module, and splitter module that divide the beam into multiple high power, and one low power channels. The beams are then focused into fibers to transmit the optical pulse to the optical detonators. The low power channel can be used for monitoring timing and/or energy. No active cooling is required since it is designed for low repetition rates. The system is designed to be rack mounted, requiring only 110 V AC power and rugged enough to be transported to various test sites without further alignment. One of the unique aspects of this system is the incorporation of numerous safety features to prevent accidental release of optical or electrical energy, mirroring safety themes required for electrical firing systems.
