Abstract

In this work, we report the optical properties of Tm³⁺ doped lead-niobium-germanate glasses (GeO₂-PbO-Nb₂O₅) for different Tm³⁺ concentrations ranging between 0.5 and 3 wt%. Judd-Ofelt intensity parameters have been determined to calculate the radiative transition probabilities and radiative lifetimes of excited states. Luminescence spectra and lifetimes were measured under 457 nm and 798 nm excitations. In this glass the infrared emission corresponding to the ³H₄→³F₄ transition is broader by nearly 40 nm if compared to fluoride glasses used for S- band amplifiers. The stimulated emission cross-section has been determined from the line shape of the emission spectra and the lifetime of level ³H₄.
