We propose and demonstrate the laser cooling and trapping of Rydberg-dressed Sr atoms. By off-resonantly coupling the excited state of a narrow ($\SI{7}{kHz}$) cooling transition to a high-lying Rydberg state, we transfer Rydberg properties such as enhanced electric polarizability to a stable magneto-optical trap operating at $less than \SI{1}{\upmu K}$. {\nj Simulations show that it is possible to reach a regime where the long-range interaction between Rydberg-dressed atoms becomes comparable to the kinetic energy, opening a route to combining laser cooling with tunable long-range interactions.

里德堡式磁光阱

我们提出并证明了雷德堡修饰的Sr原子的激光冷却和俘获。通过将窄的（$ \ SI {7} {kHz} $）冷却跃迁的激发态非共振耦合到高处的Rydberg态，我们将Rydberg特性（例如增强的电极化率）转移到稳定的磁光陷阱操作中的价格低于\ SI {1} {\ upmu K} $。{\ nj仿真表明，有可能达成一种机制，使里德堡级原子之间的长距离相互作用变得与动能相当，从而为将激光冷却与可调的长程相互作用相结合开辟了一条道路。
