Abstract : This review critically examines the current state of technology of laser ignition of explosives pyrotechnics and propellants. It presents the approaches used for each energetic material, looks at the materials tested, the results obtained and the potential for future development of in-service laser initiated ordnance. It has been concluded that the only possible approach to laser initiation of explosives in a fuze is via a laser driven flyer plate but that the current cost and size of prototypes are too great for incorporation in most practical systems. Laser ignition of pyrotechnics in terms of pyrotechnic materials and igniter design has reached a significant degree of maturity and it is only a matter of time before laser actuated pyrotechnic igniters are qualified for in-service use. For propellants, the principle application of laser ignition technology is in the assessment of the overall hazard potential of the material with respect to planned and accidental stimuli, and in the verification of ignition theories and the determination of global energetic and kinetic parameters. In general solid propellants are initiated by pyrotechnic igniters and the practical development of a direct laser initiation system for rocket or gun propellants is not considered a possibility in the short term.
