Paper Abstract

We investigate the cross relaxation parameter of Tm3+ ions in tellurite glasses over a wide range of concentrations: from 0.36 mol% up to 10 mol%. We propose a new measurement approach based on monitoring the steady-state emission spectra. The proposed method is very simple and allows to measure even very highly doped samples. The crossrelaxation parameter shows a linear dependence with respect to dopant concentration over the full investigated interval and the measured slope is 1.81x10-17 cm3 s-1 mol%-1. The linear dependence suggests a dipole-dipole interaction.
