We put forward a new optical system, which is composed of an existing axicon doublet and a
newly proposed amplitude filter. The axicon doublet consists of a positive axicon and a …

The bending bright spatial optical soliton generation in a photorefractive Fe-doped lithium
niobate (LN: Fe) crystal controlled by pyroelectric effect is demonstrated experimentally. A …

The non-diffracting Bessel beam approach was used for the first time for the elaboration of
photovoltaic tweezers. We report the trapping of dielectric microparticles of chalk (CaCO 3) …

Self-imaging beams consisting of three-dimensional intensity voids are generated via
photorefractive volume holography. Reconstruction of a volume hologram recorded at 594 …

A novel method of magnetic field assisted nondestructive optical probing of photonic lattice
structures in photorefractive crystals is demonstrated experimentally. High contrast annular …

Abstract Zr: Ho: LiNbO3 crystals with different concentrations of Zr4+ were prepared by
Czochralski method. The internal structure changes and the occupancy of doped ions were …

The optical induction of annular photonic lattices by a traveling Bessel beam has been
investigated in Methyl-red (MR) doped nematic liquid crystal (LC). Non-diffracting Bessel …

We investigate the applicability of the soft and hard apodization techniques to suppress
Bessel beam intensity oscillations through varying several parametric quantities, which …

The nonuniform 2D photovoltaic fields generated near the surface of a photorefractive Fe-
doped lithium niobate (LN: Fe) crystal by a nondiffracting optical Bessel beam with …

We experimentally demonstrated that dielectrophoretic (DEP) forces of alternating
photovoltaic fields generated near the surface of a photorefractive Fe-doped lithium niobate …
