This paper presents the results of an investigation of the impact of laser-induced shock on basalt samples in a water confinement regime. In order to observe the effect of laser shock-wave propagation, in this material, the rear free surface velocity is measured by a velocimetry interferometer system for any reflector under various specified conditions. Parameters for an elastoplastic constitutive law and the Kanel's damage model are provided and have been set up in such a way to ensure good correlation between numerical simulations and laboratory experiments. These resultant material properties, identified for the basalt sample studied here, could be used in future investigations looking to further correlating residual effects in material with pressure levels induced by water confined laser-matter interaction. This is of particular importance in meteoritics and planetary science due to the fact that hypervelocity impacts represent a major event taking place in the solar system, and shock waves generated during hypervelocity impacts can significantly affect physical properties of extraterrestrial materials and solid solar system bodies such as Mars, the Moon, asteroids, and others.
