The holographic reconstruction of objects typically assumes that the object is axially thin. Here, we demonstrate a simple approach that works for axially-thick potentials which evolve dynamically. Results are verified by reconstructing linear scattering experiments.
We observe the propagation of 1D Airy beams through an unbiased photorefractive crystal. For ordinary polarization, the beam diffracts, while for extraordinary polarization it experiences nonlinearity through charge diffusion and has its diffraction suppressed.
