研究了由相同真空模式耦合到较低能级的两个上能级衰变过程之间的量子干涉，并研究了其对自发发射光谱的影响。这种干扰会导致光谱变窄和光谱中的黑线。由于干扰，上层的人口不是简单的指数衰减。
Quantum interference between decay processes from two upper levels, which are coupled by the same vacuum modes to a lower level, have been investigated and its effects on the spontaneous emission spectrum have been studied. The interference can result in spectral narrowing and a black dark line in the spectrum. The population in the upper levels is not a simple exponential decay due to the interference.
