| 摘 要： | 考虑双激发态三能级原子系统，探讨了该系统小电磁感应透明的非线性理论。得到由于探测场非线性项的影响，尽管此时介质对探测光的透明依然存在，但是介质的色散率减小，从而使得探测光在介质中传播时，其群速度变大。

| Abstract: | The nonlinear behavior of electromapnetically induced transparency in an excitedstate doublet three-level atomic system has been studied.It is shown that although thetransparency to a probe field still persists at zero detuning,the dispersion of the mediumdecreases because of the nonlinear effect of the probe field,and the group velocity becomeslarger as the probe field intensity increases. |
