Starting from the nonlinear Schrodinger equation and by means of split-step Fourier numerical simulation,we study the propagation characteristics of Airy-Gaussian (AiG) beams in a photorefractive media. The results show that a specific set of parameters can result in soliton with periodic oscillation in the photorefractive media. The bigger the nonlinear factor is, the shorter the distance required to form soliton is, and the smaller the oscillation period of the soliton is. When the initial incident power of the Airy-Gaussian beam is within a certain range, the stable soliton can form. In the process of soliton formation, local energy competition leads to beam splitting. In addition, we also check the stability of the beam by perturbing the initial Airy-Gaussian beam.
