Аннотация
© 2021 Cambridge University Press. All rights reserved.We present an experimental study of the dynamics of shocks generated by the interaction of a double-spot laser in different kinds of targets: simple aluminum foils and foam-aluminum layered targets. The experiment was performed using the Prague PALS iodine laser working at 0.44 um wavelength and irradiance of a few 10"W/cm2. Shock breakouts for pure AI and for foam-AI targets have been recorded using time-resolved self-emission diagnostics. Experimental results have been compared to numerical simulations. The shocks originating from two spots move forward and expand radially in the targets, finally colliding in the intermediate region and producing a very strong increase in pressure. This is particularly clear for the case of foam layered targets, where we also observed a delay of shock breaLout and a spatial redistribution of the pressure. The influence of the foam layer doped with high-Z (Au) nanoparticles on the shock dynamics was also studied.
