TLDR
In this paper, the authors reported an experimental observation of resonant four-wave mixing in cold Rb atoms, which is a type of slow-light four wave mixing at low light intensities.Abstract:
Electromagnetically induced transparency in a four-level atomic system suppresses the linear susceptibility and enhances the nonlinear susceptibilities, which leads to the resonantly enhanced slow-light four-wave mixing at low light intensities. We report an experimental observation of such resonant four-wave mixing in cold Rb atoms.read more

High conversion efficiency in resonant four-wave mixing processes.
