英文摘要	Er3+-doped fluoroaluminate glasses with different concentrations were prepared by using melt-quenching method. Under a 638 nm laser diode pumping, efficient 3.5 mu m emission was observed in the 18 mol% Er3+ doped sample, which was ascribed to the Er3+: F-4(9/2)-> I-4(9/2) transition. The fluorescence properties such as radiative transition probability, energy level lifetime and branch ratio were predicted by the well-known Judd-Ofelt theory, while the emission and absorption cross-sections were calculated using the Fuchtbauer-Ladenburg and McCumber theories, respectively. Both simulated and experimental results show that Er3+-doped fluoroaluminate material is a promising gain medium for 3.5 mu m laser applications.
