摘　　要：介绍一种制作Yb3+/Er3+共掺杂玻璃样品的工艺。实验测量和分析了Yb3+/Er3+玻璃样品的荧光光谱和吸收谱。对Yb3+/Er3+系统的能量转移以及978nm波长泵浦下不同Yb3+/Er3+浓度配比样品的光谱特性进行了讨论。结果表明,当Yb3+浓度为Er3+浓度(0.5at.%)的9倍时,荧光强度最强。The laser glasses with high Yb3+/Er3+ dopant were prepared. The absorption and fluorescence emission spectra were measured and discussed. The energy transfer and the effect of changing concentrations of Yb3+ and Er3+ ions on spectroscopic properties were investigated, pumping at 978 nm. The highest intensity of fluorescence was obtained as the concentration of Yb3+ ions is 9 times to that of Er3+ ions.
