原子相干效应是光与物质相互作用的结果,它导致了一系列重要的物理现象。目前原子相干的实验研究工作主要在原子气体中开展,而与之相比固体材料中的相关实验研究具有更实际的应用前景。本文系统介绍了近年来固体材料中原子相干效应的研究进展,主要涉及电磁感应光透明、光速减慢与相干存储、存储光信息的可控制擦除、基于光存储的全光路由、双光脉冲的速度减慢和可逆存储和基于原子相干的增强四波混频等基本内容,最后还讨论了其在相关领域的应用。

Atomic coherence is the result of interaction between light and materials,which leads to many important physical phenomenon.Currently,most experimental researches on atomic coherence are reported in atomic gases.Compared with atomic gases,the related experimental researches in solid materials have more practical applications.This paper introduces the recent research progress of atomic coherence in solid-state materials in detail,including the Electromagnetically Induced Transparency(EIT) in solid materials,light velocity reduction and coherent storage,controllable eraser of optical storage information,all-optical route based on optical storage,optical velocity reduction and reversible storage of double light pulses and enhanced four-wave mixing based on atomic coherence,it also discusses its application to relative fields.
