We report experimental observation of three-field noise correlation between two coexisting four-wave mixing (FWM) signals and the probe signal in a coherently-prepared rubidium vapor system. The two FWM signals in a double-Λ type quasi-four-level atomic system are obtained in different directions via their respective phase-matching conditions and can be detected individually. These signals and the probe beam are found to be strongly correlated or anticorrelated with each other.
我们报告了在相干铷蒸汽系统中，两个共存的四波混频（FWM）信号与探测信号之间的三场噪声关联的实验观察。通过各自的相位匹配条件，在双Λ型准四能级原子系统中获得了两个在不同方向上的 FWM 信号，并且可以单独检测到这些信号和探测光束彼此之间存在强烈的关联或反关联。
