Electromagnetically induced transparency in a four-level atomic system driven by three coupled fields

研究了被三个耦合场驱动的四能级原子系统的自发辐射 ,通过计算自发辐射场对应的原子极化率 ,发现在某些特定参数下系统具有电磁感应透明的特性 ,同时发现电磁感应透明效应产生时 。

We study the spontaneous emission in a four level atomic system driven by three coupled fields. We have demonstrated the existence of electromagnetically induced transparency (EIT) with a set of suitable parameters, and we find that the light levels of the drive fields are as weak as that of the spontaneous emission with the EIT.
