本文报道了在1064 nm激光波长下测量~（85）Rb原子5D ~（3/2）态的动态（ac）标量极化率。与最近在Phys. Rev. A 104，063304（2021）中的测量相反，实验是在低强度状态下进行的，其中ac位移小于5D3/2态的超精细结构，如在许多冷原子实验中所使用的那样。提取的交流极化率为α5D3/2=−499±59 a.u.，在上述结果的不确定性范围内。通过分析D1线的光位移进行的1064 nm光强度的校准是不确定性的主要来源。我们的研究结果对Rydberg原子和分子的计量学、量子传感和基础物理研究等方面的应用有一定的参考价值。
We report a measurement of the dynamic (ac) scalar polarizability of the 5D3/2 state in 85Rb atoms at a laser wavelength of 1064 nm. Contrary to a recent measurement in Phys. Rev. A 104, 063304 (2021), the experiments are performed in a low-intensity regime in which the ac shift is less than the 5D3/2 state’s hyperfine structure, as utilized in numerous experiments with cold, trapped atoms. The extracted ac polarizability is α5D3/2=−499±59 a.u., within the uncertainty of the aforementioned previous result. The calibration of the 1064 nm light intensity, performed by analyzing light shifts of the D1 line, is the main source of uncertainty. Our results are useful for applications of the Rb 5D3/2 state in metrology, quantum sensing, and fundamental-physics research on Rydberg atoms and molecules.
