Abstract

The spatial profile, as well as ion-velocity distribution of laser-produced plasmas can be controlled experimentally by varying the time-form of laser pulse. A compression of nearly all produced plasma into a thin monovelocity spherical shell has been observed for the first time. A hydrodynamic numerical simulation shows that the shell generates due to special dynamics of ion ablation and geometry of experiment.
