Electromagnetically induced grating in a three-level Ξ-type system driven by a strong standing wave pump and weak probe fields

Abstract

We have analysed the properties of an electromagnetically induced grating formed in a Ξ-type three-level atomic system in the presence of a standing wave pump and travelling wave probe fields at resonant and off-resonant two-photon absorption. We have also shown the validity of this grating in an inhomogeneously broadened regime.
