Formation and propagation of Bessel beams: practical considerations

Abstract: Bessel beams belong to a class of propagation invariant, structured laser beams, and are used in various applications, including particle micro-manipulation, optical coherence tomography, optical metrology, and high resolution microscopy. In practice, Bessel beams are produced by optical fields with finite lateral dimensions propagating through finite aperture optical components, such as axicons. However, field distortions and component misalignments influence the shape of the resulting beams. In this paper, w… Show more

“…This type of wavefront modifications is commonly employed to produce Bessel type beams, with the central node preserving its lateral size within a certain range along the propagation direction [15][16][17]. Figure 1 presents the schematic layout of Bessel beam formation through the use of a refractive axicon.…”
