International audience; We study the crossover between the diffusive and quasi-ballistic regimes of random lasers. In particular, we compare incoherent models based on the diffusion equation and the radiative transfer equation (RTE), which neglect al

We present theoretical and experimental results of Le´vy flights of light originating from a random walk of photons in a hot atomic vapor. In contrast to systems with quenched disorder, this system does not present any correlations between the posi

Here, we report the experimental observation of random lasing in a controlled atomic vapor. We use Raman gain in a laser-cooled atomic cloud. By tuning the gain frequency in the vicinity of a scattering resonance, we observe an enhancement of the lig
