An experiment was performed using the PALS laser to study laser-target coupling and laser-plasma interaction in an intensity regime <= 10(16) W/cm(2), relevant for the "shock ignition" approach to Inertial Confinement Fusion. A first beam at low intensity was used to create an extended preformed plasma, and a second one to create a strong shock. Pressures up to 90 Megabars were inferred.

Abstract
An experiment was performed using the PALS laser to study laser-target coupling and laser-plasma interaction in an intensity regime <= 10(16) W/cm(2), relevant for the "shock ignition" approach to Inertial Confinement Fusion. A first beam at low intensity was used to create an extended preformed plasma, and a second one to create a strong shock. Pressures up to 90 Megabars were inferred. Our results show the importance of the details of energy transport in the overdense region. (C) 2014 AIP Publishing LLC.File in questo prodotto:
