抄録

We report the superior properties of cylindrical vector beams such as radially and azimuthally polarized beams realized under tight focusing condition. A higher-order radially polarized Laguerre-Gaussian beam has a capability of producing a much smaller focal spot compared to a conventional linearly or circularly polarized beam. On the other hand, a higherorder azimuthally polarized mode beam can produce a smaller dark spot at the focus. We utilize these features to significantly enhance the spatial resolution in laser scanning microscopy.
