在环形激光器的研究中，通过在速率方程中加入唯象耦合项来分析后向散射。然而，很难定量地估计锁定现象与后向散射反射之间的关系。行波与其后向散射波之间的相位关系也没有得到澄清。为了克服这些问题，本文推导了环形激光器的速率方程。将电场和偏振的空间分布函数表示为以幅度反射率R为参数的行波及其背向散射波的叠加。此外，还考虑了多普勒效应和线性模式拉动。结果发现，在R>；0.03的速率方程中，除了饱和项外，干扰项也起着重要的作用，而这些干扰项在以前的工作中被忽略了。揭示了行波与其后向散射波之间的相位关系。
In research on ring lasers, backscattering has been analyzed by adding phenomenological coupling terms into rate equations. However, it has been difficult to quantitatively estimate a relation between lock-in phenomena and reflection due to backscattering. Also, the phase relation between a traveling wave and its backscattered wave has not been clarified. To overcome these problems, rate equations for ring lasers have been derived here. Spatial distribution functions for electric fields and polarizations are expressed as a superposition of a traveling wave and its backscattered wave with amplitude reflectivity R as a parameter. Also, the Doppler effect and linear mode pulling are included. Consequently, it is found that interference terms, which were neglected in previous works, play an important role in the rate equations in addition to saturation terms for R > 0.03. The phase relation between the traveling wave and its backscattered wave is also revealed.
