Abstract

The focal properties of radially polarized annular multi Gaussian beams focused with a high numerical aperture parabolic mirror are numerically investigated. The tightly focused radially polarized annular multi gaussian beam beams by a high numerical aperture parabolic mirror have possible applications in particle acceleration, optical trapping and manipulating, single molecule imaging and high resolution imaging microscopy.
