We present a theoretical and experimental study aimed at characterizing statistical regimes in a random laser. Both the theoretical simulations and the experimental results show the possibility of three region of fluctuations increasing the pumping energy. An initial Gaussian regime is followed by a L\'evy statistics and Gaussian statistic is recovered again for high pump pulse energy. These different statistical regimes are possible in a weakly diffusive active medium, while the region of L… Expand

Superdiffusive random laser
The peculiar characteristics of random laser emission have been studied in many different media, leading to a classification of the working regimes based on the statistics of spectral fluctuations.Expand
Spectral dynamics of a diffusive random laser under two photon pumping
Abstract The spectral dynamics of a diffusive random laser under two photon excitation is investigated by using an experimental set-up which allows for fine mode discrimination and time resolution.Expand
Observation of Lévy statistics in one-dimensional erbium-based random fiber laser
We report on measurements of the statistical fluctuations of the output intensity in a continuous-wave-pumped erbium-doped one-dimensional random fiber laser (RFL), with specially designed BraggExpand
Diffusive random laser modes under a spatiotemporal scope.
A new mode selection method, based on spatial filtering and ultrafast detection, which allows to separate individual lasing modes and follow their temporal evolution is presented, which explores the random laser behavior of a ground powder of an organic-inorganic hybrid compound incorporated into a di-ureasil host.

Lévy flights for light in ordered lasers
L\'evy flights for light have been demonstrated in disordered systems with and without optical gain, and remained unobserved in ordered ones. In the present letter, we investigate, numerically andExpand
Statistical outliers in random laser emission
We provide theoretical and experimental evidence of statistical outliers in random laser emission that are not accounted for by the, now established, power-law tailed (L\'evy) distribution. SuchExpand
Lévy spectral intensity statistics in a Raman random fiber laser
The statistical behavior of spectral intensity fluctuations in a Raman gain random fiber laser is investigated for the first time, to the best of our knowledge. Through a fiber Fabry–Perot tunableExpand
Robustness of replica symmetry breaking phenomenology in random laser
This work reports a first experimental study of correlations of spectral fluctuations intensity in a random laser medium where the scatterers displacement significantly changes among consecutive shots, and reveals that the replica symmetry breaking (RSB) phenomenology is robust with respect to an averaging over different realizations of the disorder.

Observation of Lévy distribution and replica symmetry breaking in random lasers from a single set of measurements
The Nd:YBO random laser system is employed to unveil the physical origin of the complex correspondence between the Lévy fluctuation regime and the replica-symmetry-breaking transition to the spin-glass phase, which unfolds new possibilities to characterize other random lasers, such as random fiber lasers, nanolasers and small lasers, which include plasmonic-based, photonic-crystal and bio-derived nanodevices.

Random-laser dynamics with temporally modulated pump
We present an experimental study of the effects of temporal modulation of the pump intensity on a random laser. The nanosecond pump pulses exhibit rapid intensity fluctuations which differ from pulseExpand
