The impact of photovoltaic and bias field on the propagation of a Gaussian beam in a photovotaic photorefractive crystal is investigated. The results show that, both the photovoltaic and bias field have notable influences on the evolution of the Gaussian beam in the photovoltaic photorefractive crystal. The evolution properties of the Gaussian beam may be changed through modulating either the photovoltaic field or the bias field.
