用Weisskopf-Wigner方法计算了两个反射率为R的平行平面镜之间原子的自发衰变，包括两个反射镜很大和很小的情况。当镜子很大且反射率很高时，原子的辐射速度比自由空间中更快，并进入镜子系统的法布里-佩罗模式。当反射镜很小时，它们对总辐射率的影响很小，但如果反射率很高，则进入所定义的少数模式的辐射会增强。得出的结论是，激光标准具的存在的影响是不够的，以证明省略的原子的耦合到非法布里-珀罗模式从原子系统的哈密顿在激光标准具。
The spontaneous decay of an atom located between two parallel plane mirrors of reflectivity $R$ is calculated using the Weisskopf-Wigner method, both when the two mirrors are very large and when they are small. When the mirrors are large and of high reflectivity, the atom radiates more rapidly than in free space and into the Fabry-Perot modes of the mirror system. When the mirrors are small, their effect on the total radiation rate is small, but radiation into the few modes defined is enhanced if the reflectivity is high. It is concluded that the effect of the presence of a laser etalon is insufficient to justify omitting the coupling of the atom to non-Fabry-Perot modes from the Hamiltonian of an atomic system in a laser etalon.
