Tight focusing of radially polarized Gaussian and Bessel–Gauss beams

Abstract

We examine the effects of tightly focusing a radially polarized beam with uniform, Gaussian, or Bessel–Gauss pupil functions. The resulting FWHM is smallest for the case of a uniform amplitude profile, while the Bessel–Gauss beam results in the largest FWHM. The uniform amplitude profile also results in an axial field component that increases fastest with increasing NA. The ratio of the axial component to the transverse component is also the greatest for the uniform pupil function. On the other hand, the Bessel–Gauss beam benefits the most from the use of an annulus.
