Résumé en anglais

Several different compositions of tellurium-thallium oxide glasses were fabricated and tested for their Raman gain performance. The addition of PbO to the glass matrix increased the surface optical damage threshold by 60-230%. The maximum material Raman gain coefficient experimentally obtained was (58 +/- 3) times higher than the peak Raman gain of a 3.18 mm thick Corning 7980-2F fused silica sample (Deltanu = 13.2 THz). The highest peak in the Raman gain spectrum of the tellurium-thallium glass is attributed to the presence of TeO3 and TeO3+1 structural units with thallium ions in the vicinity at a frequency shift near 21.3 THz.< Réduire
