dcterms:description
In this work, the properties of laser plasma produced by ablation of pure and doped targets have been studied. A KrF laser, λ0 = 248 nm and 20 ns of pulse duration, was used to induce ablation. Pure Cu, Cu with 2% of Be and Cu with 4% of Sn targets of 500 μm thickness were ablated to assess the influence of these admixture on the emission characteristics of plasma ions. The utilized laser irradiance values were 0.6, 1.2 and 2.4 108 W/cm2. It was observed that the emission of Cu ions exhibited a higher gain from the Cu/Be and Cu/Sn plasmas with respect to the pure Cu one. We also performed studies of the temperature, ion velocity and charge angular distribution for the three plasmas. Under the above conditions, the analyses of the experimental data demonstrated that the influence of these admixtures on the emission of Cu ions played a not negligible role which enhances the interest in plasmas by alloy targets.
