Abstract

Intense near-infrared emission located at 1.23 μm wavelength originating from the erbium (Er3+):4S3/2→4I11/2transition is observed in Er3+-doped fluorotellurite glasses. This emission is mainly contributed by the relatively low phonon energy of the fluorotellurite glass host (∼776 cm-1). Judd-Ofelt analysis indicates a strong asymmetry and covalent environment between Er3+ions and ligands in the host matrix. The emission cross-section was calculated to be 2.85 × 10-21cm2by the Füchtbauer-Ladenburg equation, and the population inversion is realized according to a simplified evaluation. The results suggest that the fluorotellurite glass system could be a promising candidate for the development of optical amplifiers and lasers operating at the relatively unexplored 1.2 μm wavelength region.
