Abstract
A method for measuring the target potential was used to determine the peak electron temperature of a plasma produced by the action of a lase r pulse (of 0.8 ps duration and of contrast in excess of 10(12)) on a metal target. The electron temperature increased linearly with the rad iation intensity, reaching 1 keV at 2.3 x 10(16) W cm(-2). This temper ature was independent of the polarisation of the optical field inciden t obliquely on the target. The observed effect was interpreted by inve rse-bremsstrahlung absorption in a plasma of density approaching that of a solid.
