Theoretically,the four-wave mixing process is studied according to the double-sided Feynman diagram,which can show the physical process of the atom-light interaction clearly.And the susceptibility is calculated.The line shape of the transmission of the four-wave mixing at 85 Rb D2 line is experimentally investigated,and the theoretical calculation fits well with the experimental data.The study of the line shape of the four-wave mixing process can enhance the understanding of the nonlinear process,and is helpful for the usage of four-wave mixing in the quantum information research.
