Abstract

Tight focusing properties of partially coherent radially polarized vortex beams are studied based on vectorial Debye theory. We focus on the focal properties including the intensity and the partially coherent and polarized properties of such partially coherent vortex beams through a high numerical aperture objective. It is found that the source coherence length and the maximal numerical aperture angle have direct influence on the focal intensity, as well as coherence and polarization properties. This research is important in optical micromanipulation and beam shaping.
