Abstract
⺠We report on spectroscopic properties of Er3+-doped Ga2O3âGeO2âR2O (GGR, R=Li, Na and K) glasses for 1.53 μm fiber amplifier. Effects of alkali metal ions on the thermal stability and spectroscopic properties of Er3+-doped GGR glasses have been investigated. ⺠Incorporation of alkali ions such as Li+, Na+, K+ into the system can on the one hand improve the thermal stability of the glasses, and on the other hand enhance the emission at 1.5 μm due to the 4I13/2â4I15/2 transition of Er3+ and suppress the upconversion process at the same time. This particularly works best for the case of K+ inclusion. This work might give a general idea on controlling the Er3+ luminescence by simply adjusting the glass component and find a potential laser glass applicable to developing new broadband fiber amplifier.
