论文摘要
我们通过光学拉曼转变报告了原子在光学镊子中的单个弱结合的NACS分子的相干关联。拉曼技术使用深层绑定的电子激发中间状态，在减少光子散射的同时，达到了较大的过渡偶极力矩。从两个原子以其相对运动基态开始，我们的光传递效率为69％。分子的结合能在8.83（2）g时为770.2MHz。该技术不依赖Feshbach的共振或狭窄的激发态线，并且可能允许各种分子物种逐个原子组装。
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.
