A Feynman diagrammatic representations are introduced to density matrix perturbation solutions for analyzing transient four-wave mixing technique. Using this approach, an analytical expression of the density matrix is derived for nonlinear mediums.

Keywords : Feynman diagrams; Four-wave mixing; Density matrix.
