摘要：

The growth, absorption spectra, fluorescence spectra and luminescence decay curves of Tm3+-, Ho3+-BaLaGa3O7 crystals are reported. The F-3(4)-> H-3(6) and I-5(7)-> I-5(8) IR transitions of the Tm3+-BaLaGa3O7 and Ho3+-BaLaGa3O7 crystals are broad emission bands at about 2.0 mu m; the corresponding stimulated emission cross-sections were calculated by the Fuchtbauer-Ladenburg equation, respectively. Based on the Judd-Ofelt theory, we obtained three intensity parameters and a series of spectral parameters. The energy transfer parameters between the Tm and the Ho were also calculated. These results show that these crystals are promising as tunable infrared laser crystals for the 2.0 mu m regions.
