We report a complete spectroscopic analysis of Nd 3 + -doped Gd 3 Al x Ga 5 x O 12 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 3 2 4 manifold. We also report the emission cross sections for the transitions from the F 3 2 4 manifold and a Judd–Ofelt analysis with the calculation of the spontaneous emission probabilities and the radiative branching ratios.
