Abstract

The temporal dynamics of three-photon 5S1/2 → 5P3/2 → 6S1/2 → 39P3/2 laser excitation of mesoscopic ensembles of cold Rb atoms to Rydberg states in a magneto-optical trap is studied using cw single-frequency lasers at each stage. The ensembles comprise N = 1 – 5 atoms and are detected by the method of selective field ionisation with postselection with respect to the number of atoms. The dependence of the excitation probability on the duration of the exciting laser pulses and the number of detected Rydberg atoms is investigated. At short interaction times, a linear increase in probabilities is observed, and at large times, the probabilities reach saturation, while each number of atoms has its own characteristic features. The experimental dependences are compared with the results of numerical calculations in the framework of a four-level model, and their good agreement is obtained. The conditions necessary for observing Rabi population oscillations are determined. The obtained results are important for the application of Rydberg atoms in quantum information.

冷铷原子介观系综三光子激光激发至里德伯态的动力学
利用连续波单频激光,研究了冷Rb原子在磁光阱中介观系综各阶段的5S1/2→5P3/2→6S1/2→39P3/2激光激发到里德堡态的时间动力学。该系综包含N = 1 - 5个原子,并通过选择性场电离方法对原子数进行后选择来检测。研究了激发概率与激发激光脉冲持续时间和探测到的里德伯原子数的关系。在较短的相互作用时间内,观察到概率的线性增加,而在较大的时间内,概率达到饱和,而每个原子数量都有自己的特征。在四层模型框架下,将实验相关性与数值计算结果进行了比较,得到了较好的一致性。确定了观测拉比种群振荡的必要条件。所得结果对里德伯原子在量子信息中的应用具有重要意义。
