摘要
实验研究了在铯原子介质中受激拉曼四波混频过程中,注入的探针光与所产生的共轭光的增益特性,具体比较了在探针场分别作为Stokes场和Anti-Stokes场情况下,增益随粒子数密度、泵浦光频率失谐的依赖关系,并分析了其增益谱线线型和谱宽.为进一步开展基于受激拉曼四波混频进行量子关联光束的制备提供了主要实验参数的选择参考.
Abstract
In this paper,we experimentally investigated the classic gains of injected probe and generated conjugate lights via using stimulated Raman four-wave mixing process in cesium atoms. The dependences of gain on the atomic density and pump detuning were compared when the probe was injected into the atoms as a Stokes or Anti-Stokes field,and the line shape and width of the spectrum were also discussed. This result will provide necessary information for the preparation of quantum correlation via using stimulated Raman four-wave mixing process.
