Title: Density modulation-induced absolute laser-plasma-instabilities: Simulations and theory

Abstract

Fluid simulations show that when a sinusoidal density modulation is superimposed on a linear density profile, convective instabilities can become absolutely unstable. This conversion can occur for two-plasmon-decay and stimulated Raman Scattering instabilities under realistic direct-drive inertial confinement fusion conditions and can affect hot electron generation and laser energy deposition. Analysis of the three-wave model shows that a sufficiently large change of the density gradient in a linear density profile can turn convective instabilities into absolute ones. In conclusion, an analytical expression is given for the threshold of the gradient change for a two-slope density profile, which depends on the convective gain only.
