Paper Abstract

The main spectroscopic properties of a new B-Te-Na-Si-Al:Er3+ glass are investigated. The Judd-Ofelt (JO) intensity parameters (Ωt), the spontaneous emission probabilities, the branching ratios and the radiative lifetimes for each observed Er3+-ion levels were determined. The stimulated emission cross section, the fluorescence full width at half maximum (FWHM), Δλeff, the Δλeff x σe factor, and the gain spectra of the main Er3+-ion lasing emission (4I13/24I15/2) are obtained after exciting the glass sample at 532 nm (4I15/24S3/2 ). The absorption cross section of the 4I15/2→4I13/2 transition of the Er3+-ions was also obtained from absorption spectrum of the new glass. The results are compared with those reported for other Er3+-doped oxide glasses pumped at various excitation wavelengths, indicating the new Er3+- doped boro-tellurite glass has potential properties as an optical amplifier in the C-telecommunication window (1.53 μm) and a IR tunable laser. Additionally a radiative energy transfer from the glass host to the Er3+-ions was observed at 520 nm by exciting the glass sample at 466 nm into the Er3+-ion dark region.
