Generation and focusing of radially polarized electric fields

OPT ENG 42 (11): 3088-3089 NOV 2003 Wilson T, Massoumian F, Juskaitis R

The use of radially polarized light is known to produce,when focused by a high-numerical-aperture objectivelens, a spot of light whose polarization is predominantlyaxial. We have generated accurately such radially polarizedfields, which we have coupled into a high-numerical-aperturemicroscope objective so as to produce an axially polarizedfocal spot.
