We propose a time-dependent three-dimensional numerical model which successfully explains the complex spatiotemporal dynamic of photorefractive self-focusing of an infrared beam in InP:Fe. Characteristic behaviors are in good agreement with experiments previously reported. Intensity dependence and asymmetric photoinduced index profile are explained. In addition self-trapping dynamics shows potential self-trapping response in the microsecond range.
