… Here we consider the possibility and fundamental characteristics of light self-channeling
near a slit separating two similar photorefractive crystals with a diffusion response and …

… Such a model faithfully describes experiments with so-called slit beams,22 which are widely
used in practice in investigations of soliton effects in photorefractive crystals because of the …

… slit aperture behind the photorefractive hologram) for directional detection of laser induced
ultrasonic waves. … configuration based on TWM in a photorefractive crystal (PRC) with a single …

… In our experiments, deviation of the collimated beam incident on the annular slit from ideal
plane wave behavior leads to a variation in the intensity of the Bessel beam as it propagates. …

… of a slit beam with a plane wavefront in a linear medium and in a photorefractive crystal with
… It is shown that in the latter case, despite the presence of the nonlinear term in the wave …

… However, in our experiment, the annular slit is illuminated by a spherical wave that
converges near the lens center. A small circular obstruction, S, is placed at this point to block the …

… Gradually, as the waveguide structure forms toward the end face, the path of the light wave
should become narrow so that it can pass through the slit more efficiently. Therefore, the time …

… of waves attenuates without oscillation and the second one attenuates with oscillations. It is
shown that by adjusting the temperature of a photorefractive … of a photorefractive crystal has …

… We consider a slit laser beam (transverse extent of the beam along the y axis greatly exceeds
that along the x axis) propagating in the direction of the z axis at the interface of the PRC …
