Super-resolution and non-diffraction longitudinal polarized beam

Popular Physics 2007-09-19 v1 Optics

Abstract

A method is presented for generation of a subwavelength (0.43 lambda) longitudinally polarized beam, which propagates without divergence over lengths of about 4 lambda in free space. This is achieved by controlling the amplitude, phase and polarization property of the Bessel-Gaussian field on the aperture of a high numerical aperture focusing lens.
