Vortex Shedding and Laser Ablation.

Abstract

Through a critical examination of the vortex dynamics of laser ablatively accelerated targets the author was able to explain the inhibited linear Rayleigh-Taylor growth rates, clarify the role fo the Kelvin-Helmholtz roll-up, explain the short wavelength cutoff, explain and theoretically reproduce dynamically stabilized growth rates and predict magnetic field structures throughout the overdense region which lead to a physically motivated model of thermal flux inhibition.
