Effect of a prepulse on ablation-pressure smoothing in laser heating of thin foils

The results of theoretical and experimental studies of plasma heating by nonuniform laser radiation and the symmetrizing effect of a laser prepulse on the uniformity of heating of thin foils, which simulated thin-shell laser inertial-confinement fusion (ICF) targets, are presented. The high efficien...

Description
Summary:The results of theoretical and experimental studies of plasma heating by nonuniform laser radiation and the symmetrizing effect of a laser prepulse on the uniformity of heating of thin foils, which simulated thin-shell laser inertial-confinement fusion (ICF) targets, are presented. The high efficiency of symmetrization by a prepulse was demonstrated both experimentally and theoretically.
