Abstract

The color center absorption properties of as grown and H 2 annealing Yb:YAG with different Yb 3+ doped concentration have been studied,and its concentration is not consistent with doping concentration of Yb 2O 3. The fluorescence spectra and fluorescence lifetime of Yb:YAG are measured. It is only when the doped concentration more than 10at. % that the color center has a evident quenching effect on fluorescence intensity and fluorescence lifetime of Yb:YAG.
