The Optical Beams Copropagate in Nonlocal Kerr Media

In this paper,the optical beams copropagate in nonlocal Kerr media is discussed.The coupled equations are optimized based on an approximate to the nonlocal nonlinear Schrdinger coupled equation(NNLSE).Our numerical results show that the coupled equations are in good qualitative agreement when the separation between the beam centers is 2X_0≥4.
