摘　　要：采用高温熔融法制备了Tm^ 3+离子单掺杂及Ho ^3+/Yb ^3+共掺杂的碲锗酸盐玻璃,并研究了其在2 μm波段的发光性能。在808 nm激光二极管泵浦下,在Tm^ 3+单掺杂的碲锗酸盐玻璃中获得了1.81 μm波长的荧光,荧光的半峰全宽达211 nm,发射截面为6.32×10^ -21 cm ^2。在980 nm激光二极管泵浦下,在Ho ^3+/Yb ^3+共掺杂的碲锗酸盐玻璃中获得了2.03 μm波长的荧光,荧光的最大半峰全宽为170 nm,发射截面为3.2×10 ^-21 cm^ 2。研究结果表明,稀土离子掺杂的碲锗酸盐玻璃不仅具有优良的物化性能,而且具有优良的中红外2 μm发光性能,在中红外超短脉冲激光玻璃光纤材料领域具有潜在的应用价值。In this paper, Tm ^3+ doped and Ho^ 3+/ Yb ^3+ co-doped tellurite-germanate glasses were prepared by the high-temperature melting method, and their mid-infrared fluorescence performances at 2 μm were studied. The results showed that as for the Tm^ 3+ doped tellurite-germanate glass pumped by the 808 nm laser diode, the full width at half maxium of its fluorescence at 1.81 μm was 211 nm and the corresponding emission cross-section was 6.32×10 ^-21 cm^ 2. In contrast, when the Ho ^3+/ Yb ^3+ co-doped tellurite-germanate glass pumped by the 980 nm laser diode, the widest fluorescence full width at half maximum of its fluorescence at 2.03 μm was 170 nm and the corresponding emission cross-section was 3.2×10^ -21 cm ^2. The research results demonstrate that the rare earth ions doped tellurite-germanate glass has not only the excellent physicochemical properties, but also the excellent fluorescence performances at 2 μm, which is one of the most promising gain materials for fiber lasers in the mid-infrared wavelength range.
