Abstract
Three‐halves harmonic spectra measured at three different observation angles from 0.53 μm laser produced plasmas are presented. The results are compared with existing models. On plastic targets a very good fit is obtained with Barr’s model with Te≂1.6 keV and a plasma velocity at nc/4 of v≂8.107 cm/sec. For higher Z material, the electron temperature seems to increase and Landau damping may become significant.Keywords
