Abstract
A simultaneous measurement of color temperature and shock velocity in laser-driven shocks is presented. The color temperature was measured f rom the target rear side emissivity, and the shock velocity by using s tepped targets. A very good planarity of the shock was ensured by the phase zone plate smoothing technique. A simple model of the shock lumi nosity has been developed in order to estimate the shock temperature f rom the experimental rear side emissivity. Results have been compared to temperatures obtained from the shack velocity for a material of a k nown equation of state.
