Paper Abstract

The coherent properties of the temporally and spectrally narrowed emission of organic dyes hosted inside artificial scattering matrices, after one- and two-photon excitation, were investigated by performing photon-counting measurements. The excitation source was a frequency doubled 200 femtosecond pulsed laser emitting at 400 nm for one- photon or the 800 nm fundamental emission for two-photon excitation. 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 bellow the excitation energy threshold has been investigated from the photon number distributions obtained.
