摘　　要：在包含三能级原子的环形腔的输出光场中,观察到了由电磁感应透明(EIT)效应导致的动态非稳及混沌.该动态非稳及向混沌的过渡可以通过耦合光场而加以很好地控制.同时,由三能级EIT导致的原子相干改变了系统的吸收、色散及非线性效应,从而极大地增强了系统的动态非稳和混沌过渡特性.建立了一个理论模型来定量地解释观察到的现象.Dynamic instability and chaos are experimentally observed in the output field of an optical cavity consisting of three-level atoms near the condition of electromagnetically induced transparency （EIT）. The observed dynamic instability and route to chaos can be well controlled by the coupling laser field, and are greatly enhanced by the modified absorption, dispersion, and nonlinearity due to induced atomic coherence in the three-level atomic EIT system. A theoretical model is developed to quantitatively explain the observed results .
