Abstract
The coherent properties of the temporally and spectrally narrowed emission of laser-induced fluorescence of organic dyes hosted inside artificial scattering matrices (random lasers) were investigated. The excitation source was a frequency doubled 200 femtosecond pulsed laser emitting at 400 nm. Spectral and temporal features were simultaneously recorded using a spectrograph and a streak camera operating on the photon counting mode. Photon number distributions were thus created. The temporal coherence of the laser-like emission above and below the excitation energy threshold has been investigated from the photon number distribution obtained.
