摘要: This paper proposes a new scheme for generating vortex laser beams from laser. The proposed system consists of Dove prism embedded in an unbalanced Mach-Zehnder interferometer configuration. configuration allows controlled construction p x array Ince-Gaussian modes, IG(e) (p,p) modes. An incident IG(e)(p,p) beam variety order can easily be generated end-pumped solid-state with off-axis pumping mechanism. study simulates this type generation, analytically derives the positions resulting beams, and discusses propagation effects. applied to optical tweezers atom traps form two-dimensional arrays, or used transfer angular momentum micro particles atoms (Bose-Einstein condensate).
