Résumé

A numerical hydrodynamics code post-processed by an atomic collisional-radiative model is used to calculate population inversions which occur in lithium-like ions in recombining aluminium laser-produced plasmas. Time and spatial evolution of the 5f-3d and 4f-3d population inversions in Al10+ are obtained. The investigation of these inversions according to a range of incident laser parameters emphasizes a set of optimal plasma values of electron density and temperature as well as relative abundance of He-like and Li-like ions. The laser flux density range required for the production of population inversions in Al10+ is shown to be relatively moderate (about 5.1012W/cm2). The role of the cooling of the plasma and of the "frozen ionization" is emphasized.
