The dynamic evolution of bright spatial solitons induced by the transverse shifting of the beam is investigated. Transverse shifting can result in the formation and dynamic evolution of bright spatial solitons in photorefractive materials. To explain the phenomena, a uniform theoretical physical model is proposed. Numerical analysis results show that the beam shifting has strong influence on the formation and dynamic evolution of bright spatial solitons.
