Investigation of the dynamic behavior of laser-driven flyers
- Energetic Materials and Fluid Mechanics Dept. 1512, Sandia National Laboratories, Albuquerque, New Mexico 87185-5800 (United States)
Various aspects of the dynamic behavior of laser-accelerated flyer plates (e.g., planarity, cohesion, thickness, etc.) have been examined using several high-speed optical techniques. Images of accelerating flyers have been obtained by means of fast-framing photography and with an electronic image converter streak camera operated in an image motion configuration. These data are compared to records of flyer velocity vs. time as a function of laser fluence as well as impact particle velocity measurements on lithium fluoride witness plates.'' Flyer materials examined include pure aluminum and a composite material containing a thin layer of aluminum oxide. Composite flyers exhibit superior performance due to better planarity and cohesion, increased thickness vs. displacement, and significantly higher velocity for a given driving energy. With proper tailoring of flyer properties and driving laser parameters, laser-driven acceleration of thin flyer plates offers a promising, laboratory-scale approach to quantitative studies requiring well-controlled, short-pulse shcok compression.
