Abstract
  • Optical transitions of Er3+ ion in two tellurite glasses of molar composition 5TeO2:12ZnO:10Na2O:2PbO:1Er2O3 and 75TeO2:12ZnO:10Na2O:2GeO2:1Er2O3 were investigated.The measured absorption and emission spectra were analysed by Judd –Ofelt and McCumber theories,in order to obtain radiative transition rates and stimulated emission cross sections.It was found that these glasses have high and broadband absorption and stimulated emission cross sections at 1.5 mm. For the metastable 4I13/2 level, by comparing the measured lifetime with the calculated radiative decay time, quantum effciency higher than 80%was found. (literal)
