Abstract

A non-equilibrium plasma has been produced at INFN-LNS of Catania by means of laser ablation of a tantalum target placed in vacuum and by using a 9 ns Nd:YAG laser with 900 mJ maximum pulse energy and 1064 nm wavelength. The plasma plume is emitted mainly along the normal to the irradiated target surface. Plasma characterization has been performed "in situ" with a millimetric Langmuir Probe measuring the probe current vs. the polarization voltage and the time delay from the laser shot. The analysis of the I-V curve has permitted to characterize the plasma plume in terms of electron temperature, electron density, ion current density and plasma potential.
