Direct measurement of pressure dependent nonlinear refractive index of CO2 and Xe in subcritical and supercritical states are reported. In the vicinity of the ridge (or the Widom line), corresponding to the maximum density fluctuations, the nonlinear

We have numerically found profiles of (1+1)D single and incoherently coupled nondiffracting beams in the photorefractive medium with purely diffusion nonlinearity. The main features of propagation and interaction of the nondiffracting beams are analy

The Sommerfeld diffraction theory is extended to the case of extremely short pulses. We show that in the far field the energy-density distribution of the diffractional pattern is transformed into a Gaussian distribution, when the plane wave with unif
