Direct measurement of excited-state dipole matrix elements using electromagnetically induced transparency in the hyperfine Paschen-Back regime.

Whiting, D. J. and Keaveney, J. and Adams, C. S. and Hughes, I. G. (2016) 'Direct measurement of excited-state dipole matrix elements using electromagnetically induced transparency in the hyperfine Paschen-Back regime.', Physical review A., 93 (4). 043854.

Abstract

Applying large magnetic fields to gain access to the hyperfine Paschen-Back regime can isolate three-level systems in a hot alkali metal vapors, thereby simplifying usually complex atom-light interactions. We use this method to make the first direct measurement of the |⟨5P||er||5D⟩| matrix element in Rb87. An analytic model with only three levels accurately models the experimental electromagnetically induced transparency spectra and extracted Rabi frequencies are used to determine the dipole matrix element. We measure |⟨5P3/2||er||5D5/2⟩|=(2.290±0.002stat±0.04syst)ea0, which is in excellent agreement with the theoretical calculations of Safronova, Williams, and Clark [Phys. Rev. A 69, 022509 (2004)].
