摘要：

The spectroscopic analysis of the absorption properties of the Tm3+ ion in the three fluorapatite crystals has been performed. Using the room temperature absorption data, the spontaneous emission rates, cross-sections and cross-relaxation rates have been determined using Judd-Ofelt theory. Based on emission lifetimes and emission cross-sections for the F-3(4) --> H-3(6) and H-3(4), H-3(6) transition, as well as the rate of energy transfer by cross-relaxation, the probabilities of cross-relaxation and population inversion by cross-relaxation compare favorably to other laser hosts such as YLF and YAG.
