通过外加驱动光场的调控改变腔中四能级原子介质的色散-吸收关系,从而来调控反射光和透射光的Goos-Hanchen位移.研究表明介质可同时对探测光场进行放大和吸收,在介质对探测光的吸收和放大相互抵消（即介质呈现透明特性）的区域附近,对Goos-Hanchen位移的控制比强吸收或强放大特性下要灵敏,可以实现位移的突变和增强.

The manipulation of the Goos-Hnchen shifts in the reflected and transmitted light beam through a cavity containing four-level atomic medium is investigated by modifying the dispersion-absorption properties of the intracavity medium.Via two external coherent control fields,the Goos-Hnchen shifts of the reflected and transmitted beam can be easily controlled.It is found that around the transparent region of the medium,the Goos-Hnchen shifts are very sensitive and can be enhan...
