The effects of co-doping with Cr3+ on the absorption and emission characteristics of double doped Cr3+, Nd3+:YAG (yttrium aluminum garnet) are analyzed. The multisite structure due to co-doping (samples with a large range of Cr3+ content were used) is separated from that in single doped crystals. At least seven new lines have been separated in high resolution spectra and a tentative assignment in terms of structural data is proposed. These data suggest that the energy transfer data should be analyzed in terms of inhomogeneous system. However, the measurements indicate strong migration effects. The global donor and acceptor data at 300 K show a linear dependence on donor concentration, but the decays cannot be described in terms of published theoretical models.
