Electromagnetically induced transparency (EIT) in hot atomic ensembles allows for the generation, delay, storage and retrieval of light pulses by precisely manipulating an control field that drives one of the branches in a Λ-type level scheme. Recent experiments extended the applicability to the few-photons and single photon level [1].
We aim to store and retrieve single photons which were generated by an atom-cavity-system a.k.a. photon pistol (cf. our other posters and talks) and check the retrieved photons for the preservation of their coherence properties.
The EIT process will utilise a Λ-type scheme connecting two Zeeman sub-levels of the hyperfine ground state F=1 in 87Rb.
We report on the latest status and characterization of our setup including a triple-shielded isotopically enriched 87Rb vapour cell with Ne as buffer gas.
