We investigate self-focusing in bulk media with anisotropic nonlocal photorefractive response. Analytical results demonstrate the possibility of the existence of anisotropic soliton solutions. Self-focusing of Gaussian beams and their convergence to elliptically shaped soliton solutions is investigated theoretically and demonstrated experimentally.
