“…In 2018, Halder and Koivurova et al [12] introduced a class of Bessel-correlated fields using the theory of the shifted elementary beam, which appears under certain conditions with nearly invariant properties and a self-Fourier transform. The propagation of these beams in free space and under atmospheric turbulence has also been studied [13]. An important application of these beams is particle processing, which requires randomly changing the distance between the source and particle.…”

We investigate the propagation characteristics of partially coherent multi-Gaussian Schell-model (MGSM) and modiﬁed Bessel-correlated (MBc) vortex beams traveling in a turbulent plasma. Based on the extended Huygens-Fresnel principle, the cross-spectral density expressions for partially coherent MGSM and MBc vortex beams propagating through turbulent plasma were derived. The results show that the dark spot at the center of the partially coherent MGSM beams disappears in the low-coherence states and remains in the high-coherence states only. In contrast, the intensity of partially coherent MBc vortex beams exists in low- and high-coherence states and does not change during propagation in a weak turbulent plasma.

In this paper, the radially polarized new kind of power-exponent-phase vortex (NPEPV) beam, with rotationally symmetrical phase structure, was introduced and the tightly focused properties of the radially polarized NPEPV beam passing through a high numerical aperture objective lens were studied numerically. The results show that with the increase of topological charge l, there are multiple intensity points in the focal region, and the number is consistent with the topological charge. In addition, as the power order n increases, the light intensity gradually concentrates on the central optical axis and the surrounding intensity points gradually disappear, which finally presents a Gaussian intensity distribution with the dark cores gradually move away from the optical axis and disappear. These unique properties will have potential applications in particle trapping and laser fabrication, especially for simultaneous trapping of multiple particles and fabrication of chiral microstructures.
