Electromagnetically induced absorption in a non-degenerate three-level ladder system.

Whiting, D. J. and Bimbard, E. and Keaveney, J. and Zentile, M. A. and Adams, C. S. and Hughes, I. G. (2015) 'Electromagnetically induced absorption in a non-degenerate three-level ladder system.', Optics letters., 40 (18). pp. 4289-4292.


We investigate, theoretically and experimentally, the transmission of light through a thermal vapor of three-level ladder-type atoms, in the presence of two counterpropagating control fields. A simple theoretical model predicts the presence of electromagnetically induced absorption in this pure three-level system when the control field is resonant. Experimentally, we use Rb87Rb87 in a large magnetic field of 0.62 T to reach the hyperfine Paschen–Back regime and realize a nondegenerate three-level system. Experimental observations verify the predictions over a wide range of detunings.
