Abstract

Spectroscopic properties and the gain of the 1.6 μm emission in selenide and chalcohalide glasses doped with Ho3+ were investigated. Intense 1.6 μm emission with high quantum efficiency was observed from both glasses. Tb3+ ions were codoped to depopulate the Ho3+: I75 level and resulted in the population inversion between the I55 and I75 levels. Estimation of the gain coefficient indicated that a positive gain over the entire U -band window is possible in Ho3+ / Tb3+ -codoped selenide glasses. Selective energy transfer from the selenide host glass to the Ho3+: I75 level resulted in a strong 2.0 μm emission.
