The transfer mechanisms occurring in ytterbium, thulium and holmium doped gadolinium gallium garnet crystals are presented. Various models are used to modelize the up- and down-conversion processes. They lead to a good description of the excited state dynamics and provide information about the efficiencies of the transfers. |
