Paper Abstract

The influence of sodium ions on rare-earth clustering formation was analyzed in xSiO2-(1-x)P2O5-zNa2O glass matrices observing variations in the erbium lifetime laser tradition at 1535 nm. The ER3+ equals 1.0M glasses have shown an optimal performance for sodium close to 0.5M. Using the fluorescence characteristics an enhancement of approximately 25 percent in the lifetime was observed. It was noticed that the Na+ ions have not contributed only to the clustering formation but also to the rare-earth concentrating, due to the augment in the non- bridging oxygen in the glass. The Judd-Ofelt analysis was applied to the glass system and softening due to the inclusion of sodium into the matrix was observed. All these results are in agreement with the molecular dynamics analysis reported for similar glass.
