Based on conservation laws, kinetic equations for changes in ion populations in different energy states are written down, as well as equations how optical radiation intensity (and power) is changing in the optical fiber core is sequentially derived. Physical limitations of the given approach are also considered. A comparison of the results of a numerical analysis of the formation of luminescence in the ytterbium-doped optical fiber (with different representations of the probability of “survival” of spontaneous emission photons) with experimental data is presented.

掺fiber光纤放大器的理论平衡模型

根据守恒定律，写下不同能量状态下离子种群变化的动力学方程式，以及依序推导光纤芯中光辐射强度（和功率）如何变化的方程式。还考虑了给定方法的物理局限性。给出了掺experimental光纤（具有不同的自发发射光子“存活”概率的表示）中的发光形成的数值分析结果与实验数据的比较。
