Abstract

The impact of a laser prepulse on the expansion of plasma heated by a strongly non-0uniform main laser pulse is studied experimentally by a side-on shadowgraphy. Our numerical simulations reproduced well the qualitative features of the observed plasma expansion and the smoothing effect of the prepulse .The numerical model identifies sharp contact boundaries between the colliding plasma streams, that are only gradually relaxed with the advancing time.
