Abstract

Abstract

We investigate the spatial and temporal correlations of hot-electron generation in high-intensity laser interaction with massive and thin copper targets under conditions relevant to inertial confinement fusion. Using Kα time-resolved imaging, it is found that in the case of massive targets, the hot-electron generation follows the laser pulse intensity with a short delay needed for favorable plasma formation. Conversely, a significant delay in the x-ray emission compared with the laser pulse intensity profile is observed in the case of thin targets. Theoretical analysis and numerical simulations suggest that this is related to radiation preheating of the foil and the increase in hot-electron lifetime in a hot expanding plasma.
