Abstract

We experimentally demonstrate the vortex solitons of four-wave mixing (FWM) in multi-level atomic media created by the interference patterns with superposing three or more waves. The modulation effect of the vortex solitons is induced by the cross-Kerr nonlinear dispersion due to atomic coherence in the multi-level atomic system. These FWM vortex patterns are explained via the three-, four- and five-wave interference topologies.

摘要

我们通过叠加三束或更多光束产生的干涉图样，在多能级原子介质中通过实验证明了四波混频（FWM）的涡旋孤子。多能级原子系统中由于原子相干性导致的交叉克尔非线性色散，引发了涡旋孤子的调制效应。这些FWM涡旋图样通过三波、四波和五波干涉拓扑结构得以解释。
