摘要：
When the two middle levels in a four-level ladder atom are coupled with a ground and a excited levels by the same vacuum radiation fields, respectively, there are two kinds of vacuum-induced coherence (VIC): V and Λ-type VIC; due to the quantum interference effects between the spontaneous decay channels. The effects of the VIC on the electromagnetically induced single- and two-photon transparency are studied by the semiclassical theory, respectively. The Λ-type VIC enhances the two-photon absorption, but has no effect on the single photon absorption; the V-type VIC suppresses the single and two-photon absorption.
