In this article, we present a preliminary study of the soft X-ray emission by a Cu plasma, obtained by focalizing a Nd:YAG/glass laser beam on a copper target at λ =532nm (second harmonic) at a laser intensity I ≈ 10 12W/cm2. The pulse duration is tL=6ns and the laser shot energy EL ranges from 200 to 300mJ. We have measured the average X-ray spectral emission and determined the X-ray conversion efficiency, (% 2 π sr) in the aluminum transmission window at 70eV with a harder X-ray tail at about 700eV. A study of angular distribution of X-ray intensity emitted from the plasma is presented too.
