Single-beam implementation of uniform and non-uniformly polarized Bessel beams
Due to its unique properties, the Bessel beam has a wide range of applications in numerous fields. Currently, researchers are devoting themselves to developing methods capable of dynamically controlling the polarization state. However, extracting andcontrolling the polarization state modes of arbitrary orders from a single incident beam has always been a challenge. This paper proposed a novel method based on the mode extraction principle of the optical pen, which successfully generated Bessel beams with uniform and non-uniform polarization states, thus overcoming this difficulty. This method did not require changing the polarization state of the incident vector beam. Instead, it directly extracted Bessel beams with arbitrary polarization modes from high-order vector vortex beams. By utilizing the optical pen technology, the number, position, amplitude, and phase of vector Bessel beams could be arranged flexibly. The experimental results were in high agreement with the theoretical predictions. This research not only holds great significance for the in-depth understanding of the polarization characteristics of Bessel beams but also is expected to promotetechnological advancements in fields such as optical imaging, optical communication, and particle manipulation.
