Paper Abstract

Interest in beams containing phase singularities (dark beams) is evolving as applications are being realized, in particular for high-resolution microscopy and measurements. While these dark beams are usually generated with the help of diffractive elements, in this paper two new approaches for the generation of dark beams within the laser cavity are proposed and investigated. Simulations demonstrate that distributions similar to dark beams can be obtained by various laser modes.
