我们展示了在电磁诱导透明窗口中四波混频的奥勒-汤斯（AT）分裂，这是由一个三光子过程和一个五光子过程之间的相消干涉导致的。一次和二次AT分裂是通过在一个四能级Y型原子系统中诱导原子相干性实现的。理论计算与实验测量结果吻合良好。这种对非线性光信号的可控多通道分裂在光通信和量子信息处理中可能具有潜在应用。（C）2010美国光学学会
We demonstrate Autler-Townes (AT) splitting of four-wave mixing in an electromagnetically induced transparency window, which results from the destructive interference between a three-photon process and a five-photon process. The primary and secondary AT splittings are achieved via induced atomic coherence in a four-level Y-type atomic system. Theoretical calculations fit well with the experimentally measured results. Such controlled multichannel splitting of nonlinear optical signals can have potential applications in optical communication and quantum information processing. (C) 2010 Optical Society of America
