Scientific paper

We study the possibility of creating decreasing density gradients under laboratory conditions using high-energy lasers. The idea is to study the propagation of shock waves in such laser-produced ``atmospheres'' in order to test theories on shock acceleration and shock front stability. We investigate theoretically two experimental designs that could address this question. We consider first the case of a discrete, two density step package, showing that this experiment can result in very strong shock acceleration (a factor of 4). We finally consider the case of a continuously decreasing density package, obtained by indirect illumination of a plastic target by a thin gold foil. We obtained a 20 μm thick exponential atmosphere, which is a perfect laboratory in which to study the stability of accelerating shock waves in a decreasing density gradient.
