Phys. Rev. Lett. 77, 3355–3358 (1996)Nonlinear Interaction of Light with Transversely Moving MediumReceived 29 February 1996; published in the issue dated 14 October 1996 Interaction of a light beam with matter reveals extreme sensitivity to transverse motions. Spatio-temporal delocalization of interaction and diffusive transport of light-induced perturbations is revealed through a new family of diffraction patterns. The response of the medium to the transverse motion of the light enhances near the second order phase transition point. The phenomenon has large application potential for the study of motions that are beyond the power of Doppler-effect-based methods, and suggests fundamental problems about critical processes with nonstationary influences. © 1996 The American Physical Society URL:
