英文摘要： Axially symmetric polarized beams are vector beams with spatially variant polarization, whose polarization distributions at the plane of the beam cross section take on axial symmetry. Due to their unique optical properties, such beams have many important applications in modern optics. The theoretical model for the partially coherent axially symmetric polarized beams with arbitrary polarization propagating in free space and turbulent atmosphere will be established, and the propagation properties, nonparaxiality, vectorial structure, beam quality, polarization and spatial coherence properties will be investigated. The theoretical model for the arbitrary axially symmetric polarized beams in optical trapping will be presented, and the applications of these vector beams in optical trapping will be discussed. The research findings in this project will help to the applications of these vector beams in modern optics, and improve the development of laser theory and laser technology.
