We report generation of four-wave mixing enhanced by electromagnetically induced transparency and optical pumping in a ladder-type atomic system. When two pumping laser beams are used to form a conjugate small-angle static grating, both four-wave and six-wave mixing processes are shown to exist at the same time. Interference between these two nonlinear wave-mixing signals is experimentally demonstrated.
我们报道了在阶梯型原子系统中通过电磁感应透明和光泵浦增强的四波混频的产生。当使用两束泵浦激光束形成共轭小角度静态光栅时，四波混频和六波混频过程同时存在。实验证明了这两个非线性波混频信号之间的干涉。
