“…The exceptional features imply their potential application across diverse areas like material processing, which involves tasks such as cutting and drilling [11][12][13]. Moreover, BG beams find practical utility in optical communication [14,15], including wireless underwater communication [16]. Their resilience to underwater turbulence caused by temperature and salinity makes them a robust choice for communication in such environments.…”

The orbital angular momentum (OAM) associated with structured singular beams carries vital information crucial for studying various properties and applications of light. Determining OAM through the interference of light is an efficient method. The interferogram serves as a valuable tool for analyzing the wavefront of structured beams, especially identifying the order of singularity. In this study, we propose a modified Mach–Zehnder interferometer architecture to effectively determine the topological charge of Bessel–Gaussian (BG) beams. Several numerically generated self-referenced interferograms have been used for analysis. Moreover, this study examines the propagation property and phase distribution within BG beams after they are obstructed by an aperture in the interferometer setup.

“…The central dark core with a helical wave front, which is formed in higher-order BBs, can create micro-size diameter fibers of a few centimeters in length in the materials via photo-polymerization [13]. Also, the orbital angular momentum of higher-order BBs can be used for free-space and underwater optical communications [14].…”

The generation of Bessel beams (BBs) and their characterization in a wide range of the electromagnetic spectrum are well established. The unique properties of BBs, including their non-diffracting and self-healing nature, make them efficient for use in material science and engineering technology. Here, I investigate the polarization components (s-polarization, p-polarization, transverse polarization, and longitudinal polarization) created in scalar BBs owing to their conical wave front. For emphasis, I provide a theoretical analysis to characterize potential experimental artifacts created in the four polarization components. Further, I provide a brief discussion on how to prevent these artifacts in scalar BBs. To my knowledge, for the first time, I can generate vector BBs in s-polarization and p-polarization via the superposition of two orthogonally polarized scalar BBs. This method of generation can provide the four well-known types of vector modes categorized in the V-point phase singularity vector modes. I suggest a suitable experimental configuration for realizing my theoretical results experimentally. The present analysis is very practical and beneficial for young researchers who seek to utilize BBs in light applications of modern science and technology.

“…Bessel beams constructed based on vector beams have more significant advantages over linearly polarized Bessel beams. For example, the imaging contrast can be significantly improved [15], background noise can be reduced [16], and the stability performance and transmission rate of communication [17,18] can be improved. Therefore, the research of vector Bessel beams has become a hot topic.…”

According to the current research on polarization generation methods, it is difficult to create multi-mode vector Bessel beams in free space by extracting arbitrary polarization modes from a single beam. This is due to the fact that the polarization and phase distributions between multiple polarization modes can interfere with each other. In this paper, the mode extraction principle is combined with the optical pen technique to extract arbitrary polarization modes from a single Bessel beam, and the number, position and phase of Bessel beams can be arbitrarily regulated to achieve the multi-mode coexistence of vector Bessel beams in free space. The experimental results are consistent with the theoretical analysis. This work is not only important for the in-depth study of vector Bessel beams, but also will facilitate the development of optical manipulation, optical communication, microscopic imaging and other applications.
