Abstract
We report the observation of conical diffraction induced by cross-phase modulation when a strong beam is copropagating with a weak beam through a cell containing dimethylsulfoxide. Pulsed laser beams at 1064 and 597 nm, in the transparency window of the material, were used. The phenomenon is attributed to third-order nonlinear susceptibility, and the ring observed at the far-field region is theoretically predicted by use of the Fresnel–Kirchhoff diffraction formalism.
