Observation of light thermalization to negative temperature Rayleigh-Jeans equilibrium states in multimode optical fibers
K. Baudin, J. Garnier, A. Fusaro +5
Although the temperature of a thermodynamic system is usually believed to be a positive quantity, under particular conditions, negative temperature equilibrium states are also poss…
Interplay of thermalization and strong disorder: Wave turbulence theory, numerical simulations, and experiments in multimode optical fibers
Nicolas Berti, Kilian Baudin, Adrien Fusaro +3
We address the problem of thermalization in the presence of a time-dependent disorder in the framework of the nonlinear Schrödinger (or Gross-Pitaevskii) equation with a random pot…
Triggering filamentation using turbulence
D. Eeltink, N. Berti, N. Marchiando +5
We study the triggering of single filaments due to turbulence in the beam path for a laser of power below the filamenting threshold. Turbulence can act as a switch between the beam…
Molecular alignment and filamentation: comparison between weak and strong field models
N. Berti, P. Béjot, J. -P. Wolf +1
The impact of nonadiabatic laser-induced molecular alignment on filamentation is numerically studied. Weak and strong field model of impulsive molecular alignment are compared in t…
