Fluorescence dynamics of Er/sup 3+/ and Ho/sup 3+/ ions and energy transfer in some fluoride glasses

A detailed study at room temperature of the fluorescence dynamics of Er/sup 3+/ and Ho/sup 3+/ ions and energy transfer processes Er/sup 3+/ to Ho/sup 3+/ in the ABLA, BATY, and BIZYT fluoride glasses is reported. Numerous concentrations and different selective laser excitations in the visible and infrared spectral ranges are used. The best concentrations and the more suitable glasses for laser applications at 2 mu m are determined.<
