开放简并二能级原子系统F_g=2F_e=1跃迁中的量子相干效应
|
摘要
文章分析了满足Fg=2Fe=1跃迁的开放简并二能级原子系统在磁场作用下的量子相干效应。该模型中,驱动场的偏振方向平行于磁场方向且与探针光偏振方向相互垂直。由于驱动场和塞曼分裂对原子的耦合作用,在不同驱动场拉比频率作用下将会分别出现电磁诱导透明(EIT)和电磁诱导吸收(EIA)效应,同时伴随相应的正常色散和反常色散。通过控制驱动场强度可以有效控制系统的量子相干效应,同时实现光速调控。
The coherence effects of the atomic ensemble with Fg=2Fe=1transition have been analyzed in the degenerate two-level system.With the magnetic field coupling,the ensemble can appear electromagnetically induced transparency or electromagnetically induced absorption with different drive field strengths.The model is valid to alter the quantum coherence effect and control the group velocity of the probe field.
