Propagation of Airy Gaussian vortex beams in uniaxial crystals

Abstract

The propagation dynamics of the Airy Gaussian vortex beams in uniaxial crystals orthogonal to the optical axis has been investigated analytically and numerically. The propagation expression of the beams has been obtained. The propagation features of the Airy Gaussian vortex beams are shown with changes of the distribution factor and the ratio of the extraordinary refractive index to the ordinary refractive index. The correlations between the ratio and the maximum intensity value during the propagation, and its appearing distance have been investigated.

Propagation Characteristics of Circular Airy Vortex Beams in a Uniaxial Crystal along the Optical Axis

“…Based on the plane-wave angular-spectrum theory, Ciattoni A. et al developed an approach addressing paraxial propagation in a uniaxial crystal [ 24 , 25 ]. Inspired by the work of Ciattoni A., studies on the propagation of airy beams in uniaxial crystals have been reported [ 30 , 31 , 32 , 33 ]. These works mainly focused on cases that were orthogonal to the optical axis, in which the two intrinsic components of the beam are not coupled and no OV is generated.…”

Propagation of Airyprime beam in uniaxial crystal orthogonal to propagation axis

“…It is stated [6] that autofocusing behaviour of circular Airy beam is observed when length of crystal is long enough. Effect of vortexity for Airy Gaussian vortex beams is studied in [7]. Focusing point shifts away when topological charge increases if radial polarization is applied to the same beam [8].…”

Propagation of chirped sinh-Gaussian beams in uniaxial crystals orthogonal to the optical axis

“…In addition to intensity, phase information of Airy Gaussian vortex beam is lost at long distance in crystal having large refractive index ratio [6]. Influence of distribution factor of Airy-Gaussian vortex beam is studied in nonparaxial analysis [7].…”
