Abstract

Emission properties of 2.0 μm fluorescence and the energy transfer between Ho³⁺ and Tm³⁺ in 57PbO.25Bi₂O₃.18Ga₂O₃ (mol%) glass codoped with Ho³⁺ and Tm³⁺ were investigated. Cross-relaxation rates in Tm³⁺ increased approximately 5 times when the Tm₂O₃ concentration was increased from 1.0 to 1.5 wt%. Coefficients of the forward Tm³⁺ → Ho³⁺ energy transfer were about 15 times larger than those of the Tm³⁺ ← Ho³⁺ backward transfer. Analysis of the energy transfer and gain spectra indicated that the highest gain at the 2.0 μm wavelength region could be achieved from the glass with 1.5 wt% of Tm₂O₃ and 0.3 wt% of Ho₂O₃.
