Abstract

Laser initiation of the various explosive materials requires a wide variety of energy densities. With funding from DARPA, Alfalight has developed a Surface-Emitting Distributed Feedback (SE-DFB) lasers. The technology allows a single laser diode to replace many of today's more complex solid state lasers in LIO applications. The highest-recorded continuous output power from a single emitter - 73 watts - is detailed along with peak pulsed powers exceeding 300 watts. Other beneficial properties such as wafer-level processing, surface output coupling and on-chip beam-shaping are among the attributes of this type of laser.
