(color online) Experimental setup for the deflection and detection of flying Rydberg sodium atoms. (a) The whole view of the experimental apparatus, (b) the schematic trajectories of atoms at two different incident parameters, (c) the electric field distribution formed by the charged pair of rods, and (d) the electric field along the y direction at z = 0 with charged voltage ± 10 V (black line), ± 20 V (red line), ± 40 V (blue line), and ± 60 V (pink line), respectively. The pair of Stark plates in panel (a) is used to selectively excite red and blue state Rydberg atoms through one-photon irradiation.
