The spatio-temporal evolution of the plasma induced by interaction of a Nd-YAG laser pulse with the surface of distilled water is described. The temporal evolution from 200 ns after the plasma creation to 2200 ns of the H{sub {alpha}} and H{sub {beta}} lines are reported. Supposing the Local Themodynamic Equilibrium (LTE), the two plasma parameters: electron density and temperature are determined, including the influence of the self-absorption on its measurements. The spatial evolution of the H{sub {beta}} intensity and of the electron density are given.
