Paper 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.
