摘要
由于两基态能级邻近简并的三能级Λ型原子系统与空场的相互作用,该原子的两个跃迁之间会产生空场诱导相干性.该相干项对原子系统的吸收和色散性质有重要影响.另外,由于空场诱导相干性的存在,原子的光学性质还与外加相干场的相位有关.
Due to the interaction of the vaccum filed with a three-level ∧-type atom, in which its lower levels are near-degenerate, there appears a vacuum induced coherence originating from the interference between the two transitions. The absorption and dispersion of the atomic system is strongly, dePendent on the vacuum induced coherence. In addition, the atomic optical property is also related to the phase of the external coherent fields due to the existence of the vacuum induced coherence.
