This poster describes a simulation of reverse saturable absorption in a solution C60 molecules using the COMSOL Multiphysics® software. The optical processes in C60 can be modeled through a five-level system. The energy states include three levels of the singlet state, coupled to two levels of an excited triplet state. The optical process is modeled with simple rate equations coupled to a propagation equation for the optical intensity, thus only the COMSOL® base package is used. A simulation of a z-scan experiment is presented.
