我们展示了一个多光子里德伯暗共振，其中系统与里德伯态耦合。这种类型的能级方案结合了与长寿命基态叠加相关的慢速和存储光脉冲的能力，以及里德伯态的强相互作用特性。对于（withor 44）中的theRydberg态和1 mm的束流，我们观察到在受传递时间展宽限制的室温原子系综中共振线宽小于100 kHz。共振在有序电场中是可切换的。讨论了在电光开关和光子相位门中的应用。
We demonstrate a multiphoton Rydberg dark resonance where asystem is coupled to a Rydberg state. This-type level scheme combines the ability to slow and store light pulses associated with long-lived ground-state superpositions with the strongly interacting character of Rydberg states. For theRydberg state in(withor 44) and a beam size of 1 mm, we observe a resonance linewidth of less than 100 kHz in a room-temperature atomic ensemble limited by transit-time broadening. The resonance is switchable with an electric field of order. Applications in electro-optic switching and photonic phase gates are discussed.
