摘要：采用高温熔融法制备了Tm3＋/Er3＋/Ho3＋共掺的铋硅酸盐50SiO2-40Bi2O3—5AlF3—5BaF2玻璃。研究了在808nm激光器（LaserDiodel激发下Tm3VEdYH03＋共掺的铋硅酸盐在2060nm处的发光性能，同时测试及分析了该铋硅酸盐玻璃的差热特性、吸收光谱及荧光光谱。根据吸收光谱以及Judd—Offet理论，计算了Ho3＋的Judd—Oflet强度参数Ω（t=2，4，6）以及Tm3＋／Er3＋/Ho3＋相应的吸收截面。铋硅酸盐玻璃中，Tm2O3、Er2O3和Ho2O3掺杂浓度分别为0．75％、1．0％和0．5％时，2060nm处Ho3＋：5I7→5I8发射峰强度达到最大。对Tm3＋／Er3＋/Ho3＋3种离子的光谱性质和离子间可能存在的能量传递也做了分析。H00在1953nm处的最大吸收截面盯。为9．08×10-21cm2，在2060nm处的最大发射截面σem为1．168×10-20cm2，辐射寿命τmea为2．75ms，具有良好的增益效应σemτ（3．212×10-20cm2。ms）。
The Tm3＋, Er3＋ and Ho3＋ co-doped bismuth silicate glasses 50SiO2-40Bi2Oz-5A1F3-5BaF2 were prepared by high-temperature melt-quenching method. The spectroscopic properties of Tm3＋, Ere＋ and Ho3＋ co-doped bismuth silicate at 2 060 nm exited by 808 nm Laser Diode were investigated. Thermal stability of the glasses, absorption spectra and fluorescence spectra of the Tm3＋, Ere＋ and Ho3＋ co-doped glass samples were measured. According to the absorption spectrum and Judd-Oflet theory, the Judd-Oflet intensity parameters of Ho3＋ Ω（t=2,4,6）, absorption cross sections of Tm3＋, Er3＋ and Ho3＋ were calculated, respectively. The measured fluorescence spectra manifest that the maximal emission intensity of Ho3＋：5I7→5I8 at 2 060 nm can be achieved at the concentration of 0.75% Tm2O3, 1.0% Er2O3 and 0.5% Ho2O3 in bismuth silicate glasses. Besides the spectroscopic properties of Tm3＋, Er3＋ and Ho3＋ separately and possible energy transfer mechanisms among Tm3＋, Er3＋ and Ho3＋ were analyzed and discussed in detail. The maximal absorption and emission cross sections of Ho3＋ are 9.08×10-21 cm2 at 1 953 nm and 1.168×10-20cm2 at 2 060 nm, respectively, with a lifetime of 2.75 ms, while large σemτ achieved （3.212×10-20 cm2- ms） suggesting its efficient application in 2 μm fiber lasers.
