Abstract

Heavily erbium-doped low-hydroxyl fluorotellurite glasses with molar compositions of (85.7-x)TeO₂ + xBaF₂ + 4.8Na₂CO₃ + 9.5Er₂O₃ (x = 38.1, 28.6, 19) were fabricated. The maximum doping concentration of erbium ions was up to 19 mol % by introducing BaF2 into the tellurite glass system. Under 980 nm excitation, intense emissions around 2.7 μm from the ⁴I_11/2 → ⁴I_13/2 transition of Er³⁺ ions were observed in these glasses. The efficient mid-infrared emission can be attributed to the existence of cross relaxation (CR) 4I_13/2 → 4I_15/2 (Er³⁺): 4I_13/2 → 4I_9/2 (Er3+) caused by high erbium concentration, low hydroxyl content, and low phonon energy. The stimulated emission cross section at 2.7 μm of 47.6TeO₂ + 38.1BaF₂ + 4.8Na₂CO₃ + 9.5Er₂O₃ glass was calculated as 1.94 × 10^-20 cm². Our results indicate that it is a promising gain medium for 2.7 μm lasers.
