“…Since Airy vortex beam has non-diffractive property, main intensity lobe regenerates itself during propagation [6]. Beam size of rectangular multi-gaussian schell-model vortex beam gets larger if topological charge increases [7]. Phase profile of off-axis hollow vortex Gauss beam is protected if negative crystal is used [8].…”

In this paper, we analyze the intensity and phase changes of cosine beam(CB) propagating uniaxial crystal orthogonal to optical axis. Received field is derived based upon Huygens–Fresnel integration. Main objective of this paper is to present intensity and phase evolution of cosine beam in uniaxial crystals first time in the literature. However, behavior of other untraditional beams is studied, reaction of cosine beam against uniaxial crystal is not studied previously. We analyze the results considering source beam settings, crystal structure, and propagation distance. Our results indicate that matrix view in intensity profile evolves into straight lines along propagation axis. In other point of view, symmetric cosine beam has constant phase at close distance and periodic oscillation is observed at middle at far distance. We believe that results of this study will be beneficial for optical tracking and other optical applications.

This study analyzes propagation properties of sine beam in uniaxial crystal orthogonal to optical axis. Huygens-Fresnel integral is solved to find the received field. Influence of source beam parameters, crystal refractive index settings, and propagation distance is analyzed in detail. Our results yield that intensity concentrates on minimum and maximum of x-axis at middle and longer propagation distances. Although, sinusoidal waveform is conserved at close distance. We hope that these results will be used in optical tracking applications.

“…In order to see the effect of topological charge, scientist concentrate their studies on vortex beams. Regarding this, an elliptical flat-topped profile is observed through a uniaxial crystal when a rectangular multi-gaussian schell-model vortex beam is pumped [25]. Besides this, random electromagnetic multi-Gaussian Schell-model vortex beams with high topological charges preserve their shapes along the propagation axis [26].…”

This paper introduces the chirped cosh-Gaussian vortex beam(CCGVB) and investigates its propagation in uniaxial crystal. The received field is obtained benefiting from the Huygens-Fresnel integral. In addition, analysis of the received field is carried out considering the variations in displacement parameter, chirped parameter, decay factor, and topological charge. Our results show that chirped parameter and decay factors place the beam in an off-axis position. These results can be beneficial for the design of optical communication systems, laser weapons, laser designators, and optical tracking while applying beam shaping.
