TLDR
This work uses a reflective geometry where a single parallel-aligned spatial light modulator device is used to spatially modulate two orthogonal linear polarizations with two axicon phase profiles to modulate the state of polarization along the line focus of the axicon.Abstract:
We generate nondiffracting Bessel beams whose polarization state varies with propagation distance. We use a reflective geometry where a single parallel-aligned spatial light modulator device is used to spatially modulate two orthogonal linear polarizations with two axicon phase profiles. Then, by adding an extra phase retardation radial profile between these linear states, we are able to modulate the state of polarization along the line focus of the axicon. We provide experimental results that demonstrate the polarization axial control with zero-order and higher order Bessel beams.read more

Exact solutions for nondiffracting beams. I. The scalar theory
TL;DR: In this paper, exact nonsingular solutions of the scalar-wave equation for beams that are non-diffracting were presented, which means that the intensity pattern in a transverse plane is unaltered by propagating in free space.

Bessel beams: Diffraction in a new light
David McGloin,Kishan Dholakia +1 more
TL;DR: In this article, the theoretical foundation of the Bessel beam is described and various experiments that make use of Bessel beams are discussed: these cover a wide range of fields including non-linear optics, where the intense central core of the bessel beam has attracted interest; short pulse non-diffracting fields; atom optics, and optical manipulation where the reconstruction properties of the beam enable new effects to be observed that cannot be seen with Gaussian beams.
