Paper Abstract

The optical properties of the Er3+ ion in Yttrium Orthoaluminate (YA103) are analyzed with a crystal-field Hamiltonian of Cs symmetry. Starting with the best-fit crystal field parameters, Bkm, the crystal field splitting schemes, the Judd-Ofelt intensity parameters, and multiplet-to-multiplet and line-to-line fluorescence branching ratios for Er3+ in YA103 have been predicted. The calculated energy levels and the Judd-Ofelt intensity parameters compare reasonably well with available experimental data. It is suggested that the present theory predicts the correct order of line-to-line intensities for the laser transitions emanating from the 453/2 manifold to 4Ij channels of Er3+ in YA1O3.
