Phase diffraction patterns optically induced by laser Bessel-like beams in photorefractive lithium niobate with a doped surface layer

Статья в журнале

The evolution of the characteristics of one-dimensional phase diffraction structures during their optical induction by bessel-like monochromatic beams in photorefractive samples of lithium niobate is studied experimentally. Both, one-dimensional (1D) and two-dimensional (2D) Bessel-like beams with different topology of 2D beam cross-sections are formed from Gaussian laser beams using the amplitude masks with rectangular and annular apertures. Also, the property of reconstructing the formed bessel-like laser beams after they have passed through an obstacle has been experimentally verified. These almost diffraction-free light fields with wavelengths of 457 and 532 nm can change the refractive indices of photorefractive lithium niobate samples and form within them the nonlinear photonic diffraction structures.
