摘要: We report on measurements of the statistical fluctuations output intensity in a continuous-wave-pumped erbium-doped one-dimensional random fiber laser (RFL), with specially designed Bragg grating scatterers. Transitions from Gaussian to Levy-like and back regime, similar those observed three-dimensional lasers, are described as input excitation power increases below above RFL threshold. Our results consistent theoretical predictions for sequence regimes systems. also discuss experimental connections photonic spin-glass behavior RFL, which displays replica-symmetry-breaking phase
