I will present an overview on nonlinear coherent processes in atomic systems employing Bragg diffraction via time delayed high-order wave-mixing processes. Some of the phenomena to be discussed include the storage of light into an atomic ensemble using either electromagnetically induced transparency (EIT) or coherent population oscillation (CPO). In particular, I will specially consider the case where the interacting light fields carry orbital angular momentum (OAM). The possibility of employing these nonlinear high-order processes to the generation of multi-photon quantum correlation is suggested and will be discussed.
