Dynamic polarizability of the Rb -state in 1064 nm light
arXiv:2208.12894 · doi:10.3390/atoms10040117
Abstract
We report a measurement of the dynamic (ac) scalar polarizability of the state in Rb atoms at a laser wavelength of 1064~nm. Contrary to a recent measurement in Phys. Rev. \textbf{A} 104, 063304 (2021), the experiments are performed in a low-intensity regime in which the ac shift is less than the state's hyperfine structure, as utilized in numerous experiments with cold, trapped atoms. The extracted ac polarizability is ~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 state in metrology, quantum sensing, and fundamental-physics research on Rydberg atoms and molecules.
