Paper Abstract

Laser beams containing singularities are gaining increased interest for applications in metrology, particle manipulation and other technological paradigms. While these beams are usually generated by external modulation of a fundamental Gaussian laser beam, it is advantageous to generate them directly within the laser resonator whenever possible. In this paper we propose and investigate the mechanism of selecting a mode possessing a linear singularity using strong diffraction coupling of two adjacent resonators using a bi-prism-like element.
