摘要：
The color center absorption properties of as-grown and H2-annealing Yb:YAG with different Yb3+ doped concentration have been studied, and its concentration is not consistent with doping concentration of Yb2O3. The fluorescence spectra and fluorescence lifetime of Yb:YAG are measured. It is only when the doped concentration more than 10 at.-% that the color center has a evident quenching effect on fluorescence intensity and fluorescence lifetime of Yb:YAG.
