Emission spectra of MgI and MgII from a plasma induced by the interaction of a laser pulse with the surface of aqueous solutions of MgCl2, were recorded by a time resolved spectroscopy method to obtain information on the processes involved in the formation and the evolution of the two different species. A kinetic model based on ion-electron recombination produced during the relaxation of the plasma is constructed with the aim to explain the origin and the temporal shift of observed Mg+ and Mg emissions. Comparison with the experimental results is presented and discussed.

ABSTRACTAn axisymmetric two-dimensional modeling of plasma expansion in background gas is carried out to provide a better understanding of pulsed laser deposition (PLD) processes. This model takes into account the plasma plume dynamics just after the laser ablation pulse. It is shown that hydrodynamic behaviour and thermal relaxation of the plasma are strongly dependent on the nature and the pressure of background gas. In good agreement with experimental results backward movement of particles is clearly identified at a late expansion stage (≥ 2 μs).
