Most of the RE3+ optical lines in YAG, at low temperature and concentrations, present two interesting features: a multisite structure and Lorenz lineshape of the inhomogeneous broadened lines. The satellite structure of RE3+ ions optical spectra in high temperature YAG present a group of P satellite lines of almost equal intensity that was assigned to nonstoichiometric occupation of Al3+ octahedral sites (a) by Y3+. Up to now, no reliable explanation of the anisotropic effects of Y3+(a) on RE3+ spectra was given. In this paper an attempt is made to explain the multisite structure and lineshapes in terms of the strain field (induced by point defects) theory. The model is illustrated for the absorption line 4I15/2 implies 4S3/2 of Er3+ (1.at.%) doped in YAG.
