Popis: The technology of target preparation for direct and indirect laser irradiation is developed to study the shock compressibility of materials on the Sokol-2 and Iskra-5 laser facilities. Copper and aluminum films with a density close to that of the bulk materials are prepared by ion-beam deposition. The difference in the densities of the film and bulk materials is 0.8–1.7%, and the accuracy of density measurement is 0.4–1.5%. Processes for the preparation of porous materials (aluminum, copper, nickel, gold, etc.) are also devised. Porous cop-per samples of thickness 10–50 µm, pore size 0.1–5.0 µm, mean density 0.065–0.4 g/cm3, and porosity 20–140 are obtained. The preparation of freely suspended film targets 0.1–0.2 µm thick that are irradiated by picosecondlaser shots on the Progress-P and Elas-PS facilities is described.
