Judd-Ofelt分析进行测量的Tm 3+和Ho 3+掺杂碲酸盐玻璃的主体依赖的Judd-Ofelt强度参数提取的散装样品。然后，这些被用来计算在这个特定的材料系统的辐射率和分支比。采用速率方程方法对实验实现的~2.1 μ mTm 3 +/Ho 3+共掺碲酸盐光纤激光器进行了模拟，并提取了TeO 2-ZnO-Na 2 O（TZN）玻璃中的能量传递和上转换速率参数。仿真结果与实验数据吻合良好，表明了该方法的有效性.
Judd-Ofelt analysis is performed on measurements of bulk samples of Tm3+- and Ho3+-doped tellurite glass from which the host-dependent Judd-Ofelt intensity parameters are extracted. These have then been used to calculate the radiative rates and branching ratios in this particular material system. A rate-equation approach is then used to model an experimentally realized ~2.1 μm Tm3+/Ho3+ codoped tellurite fiber laser and extract values of the energy transfer and upconversion rate parameters in TeO2-ZnO-Na2O (TZN) glass. Excellent agreement is found between simulated and experimental data, which indicates the validity of the approach.
