| Abstract: | We study the high numerical aperture focusing properties and typical applications of axially-symmetric polarized beams (ASPBs) with high polarization orders.We calculate the field distribution near focus of an aplanatic system for incident ASPBs with different polarization orders and initial azimuthal angles, and based on the simulation results,we find some unique focusing properties of the beams,such as ever on-axis energy null,strong longitudinal field,and flowerlike intensity distribution at focus.In add... |
