Effects of laser energy and impact surface on the stopping distance in metal oxide targets laser ablation

Abstract : The aim of this paper is to study the effect of fluence on the propagating parameters of the plasma plume. Two complex metal oxide targets CaCu3Ti4O12 and Ba0.6Sr0.4TiO3 were studied at moderate fluences (1.1 to 2.5 J.cm-2) and at two oxygen pressures (10 and 30 Pa). From imaging data, we showed that the stopping distance is drastically modified whether the fluence is increased by raising laser energy or by reducing impact surface. Indeed, in the first case the stopping distance was increased, while in the second case the stopping distance was almost not influenced.
