【 摘 要 】

In this work, Yb3+-doped Gd1.4Lu0.5Yb0.1O3 optical quality ceramics were successfully fabricated for the first time, to the best of our knowledge. The absorption and emission spectra were measured, spectroscopic investigations of 1-μm emission were carried out, and optical gain properties were analysed. The stimulated-emission cross-sections were 9.7·10−21 cm2 and 3.7·10−21 cm2 (calculated using the Fuchtbauer-Ladenburg equation) at 1031 nm and 1073 nm respectively. The calculated values were close to the estimated value of emission cross-sections for other Yb-doped sesquioxides. All the results show that Yb:(Gd,Lu)2O3 ceramics can be used as a potential active medium for mid-infrared high-power lasers.
