Abstract

The emission properties of 2 µm region fluorescence of Tm3+-Ho3+ co-doped tellurite glasses are investigated. Introducing F- ions to the composition of tellurite glasses plays a positive effect on the 2 µm emission. A maximum intensity of 2 µm emission is achieved when 1.5-mol% Tm2O3 and 1-mol% Ho2O3 concentration are doped in the glasses. The emission cross section and gain coefficient of the 5I85I7 transition of Ho3+ are calculated. The emission cross section has a maximum of 1.29×10-20 cm2 at 2048 nm wavelength. The results indicate that Tm3+-Ho3+ co-doped tellurite glasses are suitable for 2 µm application.
