We observe depletion of the ground state and excited state absorption after photo-excitation. © 2008 Optical Society of America.engAbsorptionDynamicsElectromagnetic wavesElectron opticsExcited statesLasersNanostructured materialsQuantum electronicsReflectionThick filmsThin filmsElectro-opticsLaser scienceUltra-fastSemiconductor lasersUltrafast reflectivity dynamics in bis (n-butylimido) perylene thin filmsTrabalho apresentado em eventoAcesso aberto2-s2.0-51349118638
