Title: Multimode evolution of the ablative Richtmyer-Meshkov and Landau-Darrieus instability in laser imprint of planar targets

Abstract

A mode-coupling model is developed to treat the multimode evolution of the ablative Richtmyer-Meshkov (RM) and Landau-Darrieus (LD) instability in the laser imprint of planar targets. Using this mode coupling model, the multimode power spectrum of the RM and LD instability is computed. For the RM instability, mode-coupling effects lead to a broadening of the oscillatory minima found in linear RM theory. For the LD instability, mode-coupling effects generate an inverse power law spectrum.
