Yb3+ 的 2F 5/2 →2F 7/2 跃迁的受激发射截面是通过 41 种不同的氧化物、氟化物和氟氧化物玻璃在 293 K 下的吸收和发射测量确定的。跃迁到高于基态的斯塔克能级的有效峰截面范围约为 0.3 至 0.8 pm2。最大值出现在硼酸盐和磷酸盐玻璃中；最小值出现在硅酸盐和低折射率氟化物玻璃中。还报告了根据积分吸收光谱计算的辐射寿命，范围为 0.6 至 2.7 毫秒。横截面随修饰离子变化的系统变化可用于定制受激发射横截面和荧光寿命。
The stimulated emission cross section for the2F 5/2 →2F 7/2 transition of Yb3+has been determined from absorption and emission measurements of 41 different oxide, fluoride, and oxyfluoride glasses at 293 K. The effective peak cross sections for transitions to Stark levels above the ground state range from approximately 0.3 to 0.8 pm2. The largest values occur in borate and phosphate glasses; the smallest values occur in silicate and low-refractive-index fluoride glasses. Radiative lifetimes calculated from integrated absorption spectra are also reported and range from 0.6 to 2.7 ms. Systematic variations in cross sections with changes in modifier ions can be used to tailor stimulated emission cross sections and fluorescence lifetimes.
