Abstract:
A method for spectroscopy of the optical emission of a liquid excited by a pulsed laser focused on the surface thereof is such that the area of analysis is scanned by a laminar discharge of gas whose velocity and section are such that it is possible to remove the residues of the plasma suspended in the gas, resulting from a first laser pulse, before the subsequent laser pulse occurs.
