| 摘 要： | 设计了组成为0．70TeO2-(0．20-x)ZnO-xGeO2—0．05La2O3-0．025K2O-0．025Na2O-0．01Yb2O3(摩尔分数x=0,0．05，0．10，0．15和0．20)的碲酸盐激光玻璃，测试了热学性质、吸收光谱、荧光光谱和荧光寿命。计算了Yb^3 离子的吸收截面、受激发射截面、荧光有效线宽等参数。结果表明，组成为0．70TeO2-0．20GeO2-0．05La2O3-0．025K2O-0．025Na2O的玻璃具有优于著名的碲锌钠(TZN)玻璃的热稳定性，高的受激发射截面(1．23pm^2)。长的荧光寿命(0．92ms)和宽的荧光有效线宽(77nm)。通过激光性能评价。最小抽运强度为0．98kW／cm^2，表明掺Yb^3 组份的碲酸盐玻璃是实现高能短脉冲可调谐激光器的理想增益介质。

| Abstract: | A series of new multi-component glasses of 0.70TeO2-(0.20-x)ZnO-xGeO2-0.05La2O3-0.025K2O-0.025Na2O-0.01Yb2O3 (mole fraction x=0, 0.05, 0.10, 0.15, 0.20) were presented. Thermal stability of the system, spectra and laser properties of Yb3+ ions were measured. The result shows that the composition glass of x=0.20 has good thermal stability, large stimulated emission cross-section of 1.23 pm2 for the 2F5/2→2F7/2 transition, longer fluorescence lifetime of 0.92 ms, broad fluorescence effective linewidth of 77 nm and minimize pump intensity of 0.98 kW/cm2. Evaluated from the good potential laser parameters, it is desirable for high-average power and short pulse tunable laser. |
