Bound dipole solitary solutions in anisotropic nonlocal self-focusing media

We find and analyze bound dipole solitary solutions in media with anisotropic nonlocal photorefractive material response. The dipole solutions consist of two elliptically shaped Gaussian-type beams separated by several diameters, and with a $\pi$ phase shift between their fields. Spatial evolution of two initially round Gaussian beams and their convergence to the above dipole solution is demonstrated experimentally.
