我们利用磁光陷阱中冷铯原子的样品研究了非循环跃迁的非线性光谱和四波混频光学相位共轭。对于中等泵浦功率和大角度孔径，测量了1%量级的反射率。特别是，我们在三能级V型系统中进行了非线性光谱实验，直接观察到铯原子{6\mathm{S}}_{1\mathm{/}2}$，F=4基态的交流斯塔克分裂。
We have employed a sample of cold cesium atoms in a magneto-optical trap to study nonlinear spectroscopy and four-wave-mixing optical phase conjugation using a noncycling transition. Reflectivities of the order of 1% have been measured for moderate levels of pump power and large angular aperture. In particular, we have performed nonlinear spectroscopy in a three-level V-type system and observed directly the ac Stark splitting of the cesium ${6\mathrm{S}}_{1\mathrm{/}2}$, F=4 ground state.
