实验证明了在原子系综中注入Stokes光种子，使其内部态与Stokes种子相干，可以实现相位敏感的拉曼散射.这种相敏特性是由于在拉曼过程中，注入的斯托克斯光场与原子系综内部态之间的相位相关引起的干涉效应的结果。此外，相长干涉导致的拉曼效率大于其他类型的拉曼过程，如受激拉曼过程与斯托克斯种子注入单独或不相关的轻原子播种。它可以在精密光谱学、量子光学和精密测量中找到应用。
A phase sensitive Raman scattering was experimentally demonstrated by injecting a Stokes light seed into an atomic ensemble, whose internal state is set in such a way that it is coherent with the input Stokes seed. Such phase sensitive characteristic is a result of interference effect due to the phase correlation between the injected Stokes light field and the internal state of the atomic ensemble in the Raman process. Furthermore, the constructive interference leads to a Raman efficiency larger than other kinds of Raman processes such as stimulated Raman process with Stokes seed injection alone or uncorrelated light-atom seeding. It may find applications in precision spectroscopy, quantum optics, and precise measurement.
