我们报告了原子通过光学拉曼跃迁在光镊中形成单个弱束缚的NaCs分子的相干结合。拉曼技术利用深束缚电子激发态实现大的跃迁偶极矩，同时减少光子散射。从处于相对运动基态的两个原子开始，我们实现了69%的光传递效率。分子在8.83(2)G下的结合能为770.2MHz。这种技术不依赖于费什巴赫共振或狭窄的激发态线，可以允许一个原子一个原子地组装广泛的分子种类。
We report coherent association of atoms into a single weakly bound NaCs molecule in an optical tweezer through an optical Raman transition. The Raman technique uses a deeply bound electronic excited intermediate state to achieve a large transition dipole moment while reducing photon scattering. Starting from two atoms in their relative motional ground state, we achieve an optical transfer efficiency of 69%. The molecules have a binding energy of 770.2MHz at 8.83(2)G. This technique does not rely on Feshbach resonances or narrow excited-state lines and may allow a wide range of molecular species to be assembled atom-by-atom.
