研究了锂离子间的能量传递，并采用速率方程形式化进行了模拟。一个有效的能量转移从到被发现和转移和反向转移系数已被确定（和，分别）。使用速率方程的形式主义，它表明，人口反转的水平（上激光能级）是可以达到在足够低的泵浦水平，使这种材料适合于激光应用。有效的转移效率也计算，表现出良好的协议与实验值从发射的增加。
The energy transfer between and ions in lithium niobate is investigated and modelled using the rate equation formalism. An efficient energy transfer from to is found and the transfer and back-transfer coefficients have been determined ( and , respectively). Using the rate equation formalism it is shown that population inversion of the level (upper laser level at ) is attainable at sufficiently low pumping levels, making this material suitable for laser applications. The effective transfer efficiency is also calculated, showing good agreement with the experimental values obtained from the increase of the emission.
