Abstract
High resolution absorption and emission spectra of Cr4+ doped Y3Al5O12 are presented. Angular overlap model calculations for the determinati on of the energy level scheme of the Cr4+:YAG system are presented. Gr oup-theoretical considerations according to the crystal structure and the symmetry of the tetrahedrally co-ordinated Cr4+ lattice site are p resented to explain the observed dependence of the emission spectra on the direction of polarization.
