Electromagnetically induced grating in a A-type three-level atomic system modulated by a microwave field

摘要: 研究了在微波射频场调制下的Λ型三能级原子系统的电磁感应光栅现象.结果表明：微波场可以增强对探测场的相位调制和增益作用,使得衍射强度、尤其是一阶衍射强度明显提高;当系统参数取值适当时,一阶衍射强度随微波场强度呈指数增长的趋势.

Abstract: We investigate the electromagnetically induced grating in a A-type three-level atomic system with a microwave field coupling the two ground states.The results show that the intensity of diffraction,especially the first-order diffraction,is increased remarkably due to the modulation and gain of the microwave field.If the parameters of the system are chosen properly,the intensity of the first-order diffraction goes up exponentially as the microwave intensity increases.
