The interest of scientific community in laser generated plasmas is constantly growing; these plasmas allow to investigate a variety of phenomena, from material science to astrophysics issues, that are the subject of our investigation; on this purpose we measured properties of an Al plasma produced with a ND: YAG laser (1064 nm, 600 mJ, 6 ns FWHM) installed at DMFCI of Catania by means of time of flight measurements obtained by using a Faraday Cup and a Langmuir Probe; the plasma expands at different ...
