The Deflexion of the Optical Beam in the Self-defocusing Media

In this paper,dual-beam transmission problem that possess to a certainty included angle and gains the nonlinear Schrdinger coupled equation(NNLSE) in self-defocusing media is discussed.Our numerical results show that,the probe beam deflexed by the XPM of the pump beam is bigger in self-defocusing medium of nonuniform nonlinear refractive coefficient,and the power of the pump beam is comparative on the small side.
