Abstract
In this paper we report two different approaches to study the energy transfer mechanisms inside laser crystals under steady-state and dynamical conditions. The first method is based on the fluorescence Fourier analysis and is able to identify from which multiplets and through which processes the observed multiplet is populated. With the second method we analyse the decay kinetics of the fluorescences by numerical integration of a rate equation model. This analysis permits to evaluate the rate of the energy transfer mechanisms.
