We study the approach to equilibrium, described by a Gibbs measure, for a system on a $d$-dimensional torus evolving according to a stochastic nonlinear Schr\"odinger equation (SNLS) with a high frequency truncation. We prove exponential approach to

International audience; The interaction of a 600 ps laser pulse at 0.53 μm wavelength with helium gas jet with an electron density of 8×10^19 cm^−3 has been studied. In this experiment the plasma parameters for density and temperature were well-d

The influence of laser beam smoothing on stimulated Brillouin backscattering (SBBS) is studied analytically in the limit of the independent hot spot model. It is shown that the temporal beam smoothing can reduce the SBBS reflectivity significantly ev

The reflectivity due to stimulated Brillouin backscattering (SBS) from an ensemble of independent laser speckles is investigated for different speckle statistics. Calculations are based on numerical simulations with a multidimensional code and a comp

The effect of laser light self-focusing (SF) in speckles on stimulated Brillouin scattering (SBS) in an inhomogeneous plasma is studied. It is found that below but near critical power SF dramatically enhances the SBS reflectivity from an individual s

The interaction between two neighboring laser beams focused in a hot underdense homogeneous plasma is investigated using the non-paraxial wave coupling code KOLIBRI [S. Huller et al., Phys. Scr. T63, 151 (1996)] in two and three spatial dimensions. B

Numerical analysis of the system of Zakharov and electromagnetic wave equations shows that in the nonlinear stage of saturation of stimulated Raman backscattering a wide spectrum of plasma fluctuations is excited. These fluctuations manifest themselv
