摘要：

We report a complete spectroscopic analysis of Nd3+-doped Gd3AlxGa5-xO12 garnet crystal (Nd:GAGG), including absorption and emission spectra at low and room temperatures, excitation spectra showing the multisite structure of the host crystal, and temperature dependence of the lifetime of the F-4(3/2) manifold. We also report the emission cross sections for the transitions from the F-4(3/2) manifold and a Judd-Ofelt analysis with the calculation of the spontaneous emission probabilities and the radiative branching ratios.
