Electromagnetically induced transparency witha single frequency comb mode probe

We measure the electromagnetically induced transparency (EIT) of a single-frequency comb mode interacting with laser-cooled 87Rb atoms. A Λ hyperfine level structure in a D2 transition is used in the configuration of co-propagated probe (frequency comb) and coupling (continuous-wave) laser fields. The signature of EIT in the transmission of a single comb mode as well as the radiation pressure force is experimentally detected.The results are satisfactorily reproduced by the developed theoretical models, where EIT is seen to occur due to coherent accumulation. Our results could find application in quantum computing and communication with optical frequency combs.
