摘要
采用高温熔融法制备了Tm3+/Dy3+共掺杂铋酸盐玻璃样品。利用样品的差热分析曲线、拉曼光谱、红外透过光谱、吸收光谱、荧光光谱和荧光衰减曲线, 对800 nm激光二极管抽运下样品的1.47 μm宽带发光特性进行了研究。研究结果表明, 制备的铋酸盐玻璃具有良好的热稳定性、较低的声子能量和较高的红外透过率。当Dy3+的摩尔分数为0.3%时, 实现了对Tm3+的1.47 μm发光的敏化增强, 其荧光谱线的半峰全宽为118 nm。计算得到1.47 μm发光的最大受激发射截面为4.37×10-21 cm2, 光纤放大品质因子为5.31×10-26 cm3。
Abstract
The samples of the Tm3+/Dy3+ co-doped bismuth glasses are successfully prepared by the conventional high temperature melt-quenching method. By means of the differential scanning calorimetry curves, Raman spectra, absorption spectra, infrared transmittance spectra, fluorescence spectra and fluorescence decay curves of the samples, the 1.47 μm broadband emission properties of the samples pumped by 800 nm laser diode (LD) are investigated. The results show that, the prepared bismuth glasses have a good thermal stability, a low phonon energy and a high infrared transmissivity. When the mole fraction of Dy3+ is 0.3%, the sensitivity enhancement of the 1.47 μm emission of Tm3+ is achieved and the full-width at half-maximum of the fluorescence spectrum is 118 nm. The calculated maximum stimulated emission cross section of 1.47 μm emission is 4.37×10-21 cm2 and the figure of merit for the fiber amplification is 5.31×10-26 cm3.
