Paper Abstract

Visible lasers and amplifiers have potential applications in the fields of optical data storage, spectroscopy, biomedical and optical local area networks. In this study, Tb3+-Yb3+ co-doped fluorophosphate glasses were synthesized and properties of the visible emission at 0.54 µm were investigated. A upconversion excitation efficiency from Yb3+ to Tb3+ was studied by evaluations of a cooperative energy transfer efficiency from Yb3+ to Tb3+ (ηCET) and a back-transfer efficiency from Tb3+ to Yb3+ (ηBT ) which give positive and negative contribution to upconversion excitation, respectively. The ηCET was as high as 25 %, and the ηBT was less than 1 % in the fluorophosphate glass. This indicates that Tb3+-Yb3+ co-doped fluorophosphate glass is promising as new laser and gain media in the 0.54 μm band.
