Laser ablation in liquid media of noble metals. The physics of plasma plume and the optical properties of the produced colloids

In experiments of pulsed laser ablation in liquids (PLAL), performed on noble metal targets, many physical aspects regarding the characteristics of the plasma plume generated in the confining liquid, and the optical properties of the produced nanocolloids deserve a clear definition and discussion. In this paper we present the relevant theories and the results of experiments performed in our laboratory on this argument
