Abstract

Electromagnetically induced transparency (EIT) is essentially a quantum interference effect induced by two coherent laser beams exciting linked transitions in three level systems [1]. In most EIT experiments a strong coupling field of Rabi frequency Ω_c much greater than the level decay rates is used, thereby producing a well-resolved transparency window between the dressed state absorption profiles. Under these conditions the role of destructive interference between the dressed state amplitudes in producing transparency is less apparent.
