Abstract
Intra-cavity beam shaping, if properly implemented, is much more energy efficient and produces cleaner beams than the traditional external spatial modulation. Our special interest in this work is the generation of high-quality dark, or singular beams, for metrological applications. We show that bi-prism like reflectors possessing a central phase excursion within the range ±(0.3-1) π, can significantly alter the relative diffraction losses among the various oscillating modes, enabling efficient mode selection and shaping.
