Abstract
- Abstract: Yb:YAG single crystals with Yb doping concentration 5.4, 16.3, 27.1, 53.6, and 100at.% were grown by the Czochralski process. The effects of Yb concentration on the absorption spectra (190–1100nm), fluorescence spectra under 940nm and X-ray excitation were studied. The concentration quenching of fluorescence was observed when the Yb doping concentration reaches to as high as 27.1at.% for Yb:YAG. Under 940nm excitation, the influence of the self-absorption at 969 and 1029nm on the fluorescence spectra is not evident when the Yb doping concentration is as high as 27.1at.%. However, it can greatly change the shape of fluorescence spectra of Yb:YAG when the Yb doping concentration reaches to above 53.6at.%. [Copyright &y& Elsevier]
