Abstract

A Nd:YAG laser operating at 1064 nm wavelength, 9 ns pulse width, 500 mJ maximum pulse energy is employed to irradiate different metallic targets (Al, Ti, Fe, Ag) in vacuum. Optical spectroscopy and ion energy analysis are employed to characterize the laser-plasma. The plasma temperatures and densities are measured through optical spectroscopy, ion energy distributions and fast CCD imaging. Results indicated that high temperature and density gradients occur. The temperature in the core zone is in the order of 100 eV while in the coronal zone it in the order of 1 eV. The maximum plasma density is in the order of 5·1016 cm-3 in the coronal zone.
