Abstract
The three laser initiation approaches are reviewed in this report but the emphasis is put on the laser-driven flyer plate technique. For the latter technique, it is concluded that there does not exist presently sufficient theoretical and experimental data to allow selection of the optimum design parameters of the laser detonator. Among the various experimental data, many were obtained under different and often incomparable conditions such that further extensive, targeted studies are still necessary to produce a suitable HE laser detonator. The report proposes a research plan on laser-driven flyer plates combining mathematical modeling with experimental work for studying all factors important to the efficient launching of the flyer plate. It also identifies the diagnostic techniques necessary to obtain a full understanding of the launching process. The research contract provides DREV with a knowledge of the state of the art in laser initiation of HE materials. The proposed research plan gives the information that will allow DREV to decide whether or not to invest resources in laser initiaiton of HE materials.
