Paper Abstract

Method of direct oscillation at radially or azimuthally polarized transverse modes in an optical resonator is presented. The optical resonator consists of a w-axicon, a polarization controlling feedback axicon mirror, and a flat output coupler. The central axicon of the w-axicon is made to slide forward and backward relative to the outer axicon, that leads to the selection of the arbitrary order of the LG0±l Laguerre-Gaussian modes. By selectively suppressing the p-polarization or s-polarization of the axicon reflector, the oscillation modes are forced to the radially or azimuthally polarized. A preliminary experiment proves such a resonator is viable and numerical simulation predicts the oscillation characteristics of the proposed resonator.
