We show both theoretically and experimentally that nonlocality opens a route towards beam steering in our system. Indeed, the discontinuity trajectory follows a curve that bends with the injected power. Despite the stochastic nature of the medium and the constant presence of transverse instabilities, the development of a focusing shocklike dynamics is shown to survive. The distance Zs for the focusing shock to occur follows a power law with the beam power P according to Z<sub>s</sub>∝P<sup>χ</sup>, with χ=−4/3, as for shock dynamics in self-defocusing media.Lire moins >
