Use of multilayer targets for achieving off-Hugoniot states.

We present an approach for the realization of extreme off-Hugoniot states of matter in laser-driven shock experiments. The method is based on the application of impedance-mismatch effect in sandwich targets. In order to verify this model we have realized numerical simulations using the two-dimensional hydrocode multi in three-layer targets (gold-aluminum-gold) with laser intensities ∼ 10(14) W/cm(2) and obtained pressures ∼ 10 Mbar.

Coronal hydrodynamics of laser-produced plasmas.

We present the results of an experimental investigation of the temporal evolution of plasmas produced by high power laser irradiation of various types of target materials (at intensities I(L) < or = 10(14) W/cm2). We obtained interferometric data on the evolution of the plasma profile, which can directly be compared to analytical models and numerical simulations. For aluminum and plastic targets, the agreement with 1D simulations done with the hydrocode MULTI is excellent, at least for large times (t > or = 400 ps) .
