Abstract

We report on the experimental study of the excitation mechanism of fluorescence in a 10000-ppm wt. Tm⁺³-doped ZBLAN fiber. UV (at 365 nm), visible (at 453, 480 and 650 nm) and near infrared (~800 nm) radiation was observed under excitation at 1.064 μm. The responsible up-conversion mechanisms are investigated based on experimental data. The results show that the ³H₄ and the ¹D₂ levels are predominantly excited by ion-ion cross relaxation processes.
