“…A general solution of a problem on ablation-driven acceleration of a flat solid layer with initial density ρ 0 when the applied constant-intensity energy pulse evaporates the matter with density ρ a was obtained in [9]. The solution shows that the final velocity of the layer (at the moment of cessation of the energy pulse) is determined by the sound velocity of the ablated matter and the ratio of the initial and final masses of the condensed layer:…”

The results of theoretical studies and numerical simulations of laser-driven acceleration of a flat foil up to ultrahigh velocity of the order of 1000 km s −1 , which corresponds to the achievement of thermonuclear temperatures due to kinetic energy transition into thermal energy at an inelastic impact, are reported. The behavior of a foil accelerated to such high velocities, in particular, the distribution of foil density, which defines thermonuclear reaction intensity, has been studied. The calculation results are compared with the results of the experiments performed on the Gekko/HIPER laser, where a laserdriven projectile achieved record-breaking velocity. The laser pulse and foil parameters responsible for acceleration of the projectile up to 'thermonuclear' velocities in a dense state have been determined.

Criteria for replacing the real impact of a hypervelocity macroparticle by certain modelling effects have been considered. For direct modelling it has become possible to replace a high-velocity projectile by a slower one of another shape and made of material with a steeper shock adiabat (Huhoniot). The authors give calculated curves for the efficiency of the impact of various particles on different targets. Correct conditions for replacing the real particle impact by different processes are formulated in the general case of indirect modelling. They represent tentative experimental results on effects of an intensive Q-switched laser pulse upon a polycrystal target and demonstrate a possibility to achieve high shock load stresses, which are characteristic of hypervelocity impact, by laser cumulative compression of a pseudoprojectile placed on the target surface.
