Multilevel dark states: coherent population trapping by elliptically polarized (possibly incoherent) light

Valery Milner, Yehiam Prior

Summary form only given.We present here the first experimental proof for the existence of elliptical dark states (EDS), the multilevel analog of the well known three-level dark states. We demonstrate that an ensemble of multilevel atoms, when prepared by elliptically polarized light, becomes transparent to probe light of the same polarization. The effect stems from laser-induced coherences between many ground-state magnetic sublevels that reflect the polarization of the light that had created the dark state. The novelty and essential character of the dark states are elucidated by the experimental demonstration of their creation by incoherent light. The experiments were performed in a Na atomic beam.Summary form only given.We present here the first experimental proof for the existence of elliptical dark states (EDS), the multilevel analog of the well known three-level dark states.
