Emission properties of mid-infrared at 2.0 μm and 2.85 μm, and visible up-conversion as well as energy transfer mechanism between two rare earth ions, Ho3+ and Yb3+, are studied in Ho3+/Yb3+ co-doped fluorogermanate glasses pumped by a 980 nm laser diode. Enhanced mid-infrared 2.0 μm and 2.85 μm emission is obtained in fluorogermanate glass samples which is co-doped with 1% Ho2O3 and 9% Yb2O3(mole fractions). The measured decay lifetime of Ho3+ is 6.19 ms, and the theoretically calculated maximum emission cross section at 2023 nm is about 6.6×10-21 cm2. The results indicate that Ho3+/Yb3+ co-doped fluorogermanate glasses are suitable for mid-infrared 2.0 μm and 2.85 μm emission.
