摘要

研究了局限在磁光阱中的锂原子的时间分辨Rydberg激发动力学。通过分析弱探针束的吸收，测量了里德伯激发引起的中性原子损失。我们的实验证明了密度依赖性的激发阻断效应和激发促进效应的存在。此外，我们还测量了不同激励脉冲持续时间下里德伯跃迁的频移。这种频移可归因于由里德伯原子高密度系综形成的超冷离子。

Excitation Dynamics of Interacting Rydberg Atoms in Lithium Magneto-Optical Trap

We study the time-resolved Rydberg excitation dynamics for Lithium atoms confined in a magneto-optical trap. Loss of neutral atoms due to Rydberg excitation is measured by means of analyzing the absorption of a weak probe beam. Our experiment demonstrates the existence of both density-dependent excitation blockade and excitation facilitation effects. Moreover, we measure the frequency shift of the Rydberg transition at various durations of excitation pulses. This frequency shift can be attributed to the formation of ultracold ions from the high-density ensemble of Rydberg atoms.
