摘要

We present a method to precisely determine the hyperfine structure constants of the rubidium 5D5/2 and 7S1/2 states in a cascade atomic system.The probe laser is coupled to the 5S1/2 → 5P3/2 hyperfme transition,while the coupling laser is scanned over the 5P3/2 → 5D5/2(7S1/2) transition.The high-resolution double-resonance optical pumping spectra are obtained with two counter-propagating laser beams acting on rubidium vapor.The hyperfine splitting structures are accurately measured by an optical frequency ruler based on the acousto-optic modulator,thus,the magnetic dipole hyperfine coupling constant A and quadrupole coupling constant B are determined.It is of great significance for the atomic hyperfine structure and fundamental physics research.
