Yq. Yu et al., SPECTRAL CHARACTERISTICS OF ER3-ACTIVATED AND CE3+-SENSITIZED YTTRIUM-ALUMINUM-GARNET LASER CRYSTALS(), Journal of alloys and compounds, 217(1), 1995, pp. 148-150
We report in this paper the spectral characteristics of Er3+ (2 at.%)-
activated and Ce3+ (0.3 at.%)-sensitized yttrium aluminium garnet (YAG
:Er,Ce) laser crystals grown by the Czochralski technique. The absorpt
ion and emission spectra were measured at room temperature. By using a
bsorption spectra and Judd-Ofelt theory the experimental oscillator st
rengths of the Er3+ transitions in the YAG:Er,Ce crystals were calcula
ted. The energy transfer between the Er3+ and Ce3+ ions is also discus
sed.
