TL;DR: This Letter presents first experimental results of the laser imprint reduction in fusion scale plasmas using a low-density foam layer, reproducing the conditions of the initial interaction phase in the direct-drive scheme.

TL;DR: In this paper, the propagation of an ionization wave through a subcritical foam is studied under inertial confinement fusion conditions, and independent measurements of the wave velocity are compared with hydrodynamic simulations and analytical models.

TL;DR: A statistical model for forward stimulated-Brillouin scattering is developed for a spatially incoherent, monochromatic, laser beam propagating in a plasma and it is found to be well below the threshold for self-focusing.

TL;DR: In this article, the PARAX code is used to model the laser field in a standard paraxial approximation in three dimensions, and the plasma response is described by single-fluid, two-temperature, fully nonlinear hydrodynamical equations in the plane transverse to the laser propagation axis.

TL;DR: In this article, the authors present a novel imprint mitigation mechanism based on the use of underdense foams, which induce laser smoothing by parametric instabilities thus reducing the laser imprint on the CH foil.
