Resumo
This paper studies the random lasing at the critical regime of localization. A strongly
disordered optical medium composed of core-shell nanoparticles (TiO2@Silica) suspended in
ethanol solution of Rhodamine 6G conform the random laser material. Narrow peaks of
approximately equal intensity are observed on top of the classical super-fluorescence band of
random laser, indicating suppression of the interaction between the peaks modes (localized
modes). The linewidth of these peaks is lower than that of the passive modes of the scattering
medium. The classical super-fluorescence band of the random laser was measured separately
by collecting the emission at the back of the samples, showing a linear dependence with
pumping fluence without gain depletion. However, frontal emission of the random laser showed
saturation.
