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), Δλ_eff, the Δλ_eff x σe factor, and the gain spectra of the main Er³⁺-ion lasing emission (⁴I_13/2→⁴I15/2) are obtained after exciting the glass sample at 532 nm (⁴I_15/2 →⁴S_3/2 ). The absorption cross section of the ⁴I_15/2→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.
