Properties of partially coherent elegant Laguerre-Gaussian beam in free space and oceanic turbulence
, 2020The analytical expression of partially coherent elegant Laguerre-Gaussian (PCELG) beam generated by anisotropic Gaussian Schell-model sources is given. The analytical formulas of CSD for a PCELG beam propagating in free space and oceanic turbulence are ...

Beam wander of partially coherent Airy beams
Journal of Modern Optics, 2014The beam wander of a partially coherent Airy beam in a turbulent atmosphere was investigated. By using the extended Huygens–Fresnel integral, as analytical expression is derived for the second-order moment of a partially coherent Airy beam. Based on the theory proposed by Andrews, a general expression is obtained for the beam wander of a partially ...

Matrix treatment for partially polarized, partially coherent beams
Optics Letters, 1998A matrix method is outlined for dealing with quasi-monochromatic, partially polarized light when spatial coherence is not necessarily complete and propagation occurs along beams. Both spatial coherence and polarization properties are described by a single 2x2 matrix whose elements have the structure of mutual intensity functions.

Beam shaping of partially coherent beams by use of the spatial coherence effect
SPIE Proceedings, 2005We show that when a partially coherent beam with a Gaussian intensity distribution is focused by a lens, the intensity distribution near geometrical focus is strongly dependent upon the spatial coherence. Based on this, the desired intensity distribution near the focus can be generated by choosing appropriate form of spatial coherence. It is shown that

Based on the extended Huygens–Fresnel principle, the cross-spectral density function of a partially coherent anomalous hollow vortex beam (AHVB) propagating in underwater oceanic turbulence has been derived, and the influences of the beam parameters and ...

Partially coherent vortex beams
Complex Light and Optical Forces XII, 2018Beams with structured phase and beams with partial spatial coherence have both been considered for a variety of applications for many years, and it would seem natural to combine their advantageous properties. However, there is a conceptual difficulty in doing so because partially coherent beams lack a definite phase, which would seem to rule out a ...

Overview: In this chapter we study the effects of a spatially partially coherent beam. Several investigations of the properties of such beams have led to the conclusion that the use of a diffuser at the exit aperture of a coherent laser can produce reduced scintillations at the receiver under the proper conditions.

Partially coherent radially polarized circular Airy beam.
Optics Letters, 2020We propose and demonstrate a new, to the best of our knowledge, kind of partially coherent vector beam called the partially coherent radially polarized circular Airy beam (PCRPCAB).

Propagation of partially polarized, partially coherent beams
Journal of Optics A: Pure and Applied Optics, 2008The propagation of partially polarized and partially coherent beams in free space is investigated. Using the partially polarized Gaussian Schell model beam as an example, closed-form propagation expressions are derived for the intensity distribution and the degree of polarization of the beam.

Coherent and partially coherent vortex beams in turbulence
Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007The evolution of the scintillation and topological charge of coherent and partially coherent vortex beams in turbulence is analyzed. The possibility of using such beams in optical communications is discussed.
