The role of coherent population oscillations is evidenced in the noise spectrum of an ultralow noise laser. This effect is isolated in the intensity noise spectrum of an optimized single-frequency vertical external cavity surface-emitting laser. The coherent population oscillations induced by the lasing mode manifest themselves through their associated dispersion that leads to slow light effects probed by the spontaneous emission present in the nonlasing side modes.
相干种群振荡的作用在超低噪声激光的噪声谱中得到了证实。这种效应在优化的单频垂直外腔面发射激光器的强度噪声谱中被隔离出来。激光模式引起的相干种群振荡通过它们相关的色散表现出来，这导致了通过非激光边模中的自发发射探测到的慢光效应。
