Abstract

Thermal stability and broadband NIR luminescence of Pr3+ doped gallo-germanate glasses with BaF2 have been studied. The thermal factors are larger for glass samples with low BaF2 content exhibiting good thermal stability against devitrification. Luminescence due to 1D21G4 transition of Pr3+ was measured under 450 nm excitation. The 1D2 measured lifetimes depend critically on activator concentration, but remain nearly unchanged with BaF2 content. The emission linewidth, the emission cross-section, the figure of merit (FOM) and the σem x FWHM product are relatively large, suggesting that Pr3+-doped gallo-germanate glasses with presence of BaF2 are promising as gain media for broadband near-infrared amplifiers.
