Abstract: This work reports the enhanced emission at 2.7 µm in Er3+/Ho3+-codoped fluorotellurite glass upon a conventional 980 nm laser diode. The significantly reduced green upconversion and 1.5 µm emission intensity in Er3+/Ho3+-codoped samples are observed. The results suggest that the Er3+: 4I13/2 state can be efficiently depopulated via energy transfer from Er3+ to Ho3+ and the detailed energy transfer mechanisms are discussed qualitatively. The energy transfer efficiency from Er3+: 4I13/2 to Ho3+: 5I7 is calculated to be as high as 67.33%. The calculated emission cross-section in Er3+/Ho3+-codoped fluorotellurite glass is 1.82 × 1020 cm2. This suggests that Er3+/Ho3+-codoped fluorotellurite glass is a potential material for 2.7 µm fiber laser.
