Abstract
Erbium (Er)-doped barium gallo-germanate (BGG) glasses modified by TiO2 have been investigated for near-infrared luminescence applications. Luminescence at 1.5 mm asso-ciated to 4I13/2 / 4I15/2 transition of Er3 thorn ions has been examined in function of TiO2 con-centration. Several spectroscopic and near-infrared (NIR) laser parameters for Er3 thorn such as stimulated emission cross-section, luminescence bandwidth and lifetime, quantum effi-ciency, gain bandwidth and figure of merit were determined based on experiments and theoretical calculations using the Judd-Ofelt framework. Our systematic investigations indicate that Er-doped glass with molar ratio GeO2:TiO2 1/4 1:2 shows excellent lumines-cence properties and could be successfully applied to near-infrared broadband optical amplifiers.(c) 2022 The Author(s).
