We demonstrate the phenomena of the refraction and the total internal reflection of the weak signal plasmon beam from the inhomogeneity induced by the high-power reference plasmon at the interface between a photorefractive crystal and a metal. The trajectories of the signal plasmon are obtained via the geometrical-optics methods. We found that the phenomenon of the total internal reflection occurs above the critical value of the reference plasmon intensity depending on the signal plasmon initial tilt.
