原子相干性的研究进展

原子相干效应是相干电磁场与原子相互作用的产物，在量子光学领域有重要的研究价值.许多重要的物理现象都是由原子相干效应引起的.文章介绍了基于原子相干效应的电磁感应光透明、相干烧孔、双暗态、真空感应相干、部分受激拉曼绝热过程的光存储、光信息在不同通道之间的转换与擦除等现象的理论和实验研究，并简单介绍了它们的应用价值.

Atomic coherence

Atomic coherence is the result of interaction between light and atoms, and is responsible for many important physical effects. In this review we describe various phenomena caused by atomic coherence, including electromagnetically induced transparency, coherent hole burning, double dark states, vacuum-induced coherence, optical signal storage based on stimulated Raman adiabatic passage, optical information transfer and erasure between two light channels, and so forth. We also discuss their application potential.
