Sous excitation laser de forte puissance, la bande large de fluorescence du germanate de bismuth présente des trous dont la formation est reliée à un processus d'absorption saturée des divers centres émetteurs qui contribuent à la fluorescence. On montre qu'une corrélation existe entre ce phénomène et les mécanismes de transfert d'excitation et un modèle est proposé pour expliquer 1es résultats expérimentaux.Under powerful laser excitation, the wide fluorescence band of bismuth germanate shows holes the formation of which is related to a saturated absorption process of various emitting centers which contribute to the overall fluorescence. It is shown that a correlation exists between this phenomenon and the excitation transfer mecanism and ...
