摘要：

We have measured and simulated the dynamic evolution of a soliton beam that is launched into a biased photorefractive crystal with a sinusoidally oscillating incident position. Within some frequency range depending on the optical intensity, the swinging amplitude of the soliton at the output face can be larger than that at the input face. This suggests a resonance interaction between the soliton light beam and its induced waveguide. At higher frequency, the swinging soliton beam behaves like a standing wave with nodes. The experiment and the simulation show fairly good agreement.
