摘要：

The absorption and emission spectra of Tm3+ ions in gadolinium gallium garnet is reported in order to identify the Stark levels involved in pumped and laser emission processes of this system. The analysis of the laser-excited luminescence from Tm3+ multiplets 1D2, 1G4, H-3(4) to the ground manifold H-3(6) confirms the assignments of Stark levels, corresponding to D2 symmetry, obtained from absorption and provides additional information. Due to the complex multisite structure, the site-selective excitation and emission data have been also used. A parametrized crystal-field calculation, including nine parameters for D2 symmetry, fits the energy-level diagram satisfactorily.
