摘要：基于腔内极化子的量子理论,实验研究了腔内电磁诱导透明(EIT)现象。通过升高铷气室温度,使铷原子数目大量增加。当系统满足集体强耦合条件时,利用弱控制场可实现EIT以及线宽的显著压窄。随着温度的继续升高,耦合效应增强,腔线宽被进一步压窄。
Based on the quantum theory of the intracavity polaritons,the electromagnetically induced transparency phenomenon（EIT）in a cavity is investigated experimentally.By increasing the temperature of the rubidium vapor cell,a substantial increase of the number of rubidium atoms is achieved.When the collective strong coupling condition is satisfied,a weak control field is sufficient for the realization of EIT and significant narrow linewidth.With the further increase of the temperature,the collective coupling effect is enhanced and the cavity linewidth is further narrowed.
