环形腔中光晶格的简正模分裂和力学效应

Normal mode splitting and mechanical effects of an optical lattice in a ring cavity

Julian Klinner, Malik Lindholdt, Boris Nagorny, Andreas Hemmerich

摘要:

探讨了大原子样品与高精细光学腔色散相互作用时产生的原子-腔物理的新机制。通过将等量的激光耦合到纵向腔模式的每个传播方向,在光学环形谐振器内形成数百万个铷原子的稳定的远失谐光晶格。一个相邻的纵向模式,失谐约3GHz,被用来执行探测透射光谱的系统。晶格光束和探针的原子-腔耦合是色散的,耗散仅来自有限的光子存储时间。两个良好分辨的正常模式的观察表明,制度的强合作耦合。简正模光谱的细节揭示了与探针对光晶格的反作用相关的机械效应。

英文摘要:

A novel regime of atom-cavity physics is explored, arising when large atom samples dispersively interact with high-finesse optical cavities. A stable far detuned optical lattice of several million rubidium atoms is formed inside an optical ring resonator by coupling equal amounts of laser light to each propagation direction of a longitudinal cavity mode. An adjacent longitudinal mode, detunedby about 3 GHz, is used to perform probe transmission spectroscopy of the system. The atom-cavity coupling for the lattice beams and the probe is dispersive and dissipation results only from the finite photon-storage time. The observation of two well-resolved normal modes demonstrates the regime of strong cooperative coupling. The details of the normal mode spectrum reveal mechanical effects associated with the retroaction of the probe upon the optical lattice.
