title: Study of laser plasma emission from doped targets.
abstract: In this work, the characteristics of laser plasma produced by ablation of pure and doped targets are studied. An excimer KrF laser was used to induce ablation. Pure Cu, Cu with 2% of Be, and Cu with 4% of Sn targets were ablated to evaluate the influence of these admixture on the emission of Cu ions. It was observed that the emission of ions exhibited a higher gain from the Cu∕Be and Cu∕Sn targets with respect to the pure Cu one. We also performed studied of ion velocity and charge angular distribution.
