Abstract

Optical vortex possesses a ring-shaped spatial form and an orbital angular momentum, associated with its helical wavefront. In this presentation, we review the direct generation of optical vortex modes from solid-state lasers and the nonlinear wavelength extension of optical vortex modes. We also address exotic sharing of the orbital angular momentum among the generated optical vortex beams involved in the nonlinear process. Furthermore, we present diode-pumped orbital Poincaré Pr3+:LiYF4 lasers, enabling selective generation of all eigen-modes mapped on the equivalent orbital Poincaré sphere.
