Abstract

A computer-generated hologram is used for the production of high-order muultiringed Laguerre-Gaussian modes. These holograms differ front those previously reported in that they have an additional circular discontinuity. The holograms are used in transmission and are designed to convert the fundamental Hermite-Gaussian laser mode into a Laguerre-Gaussian mode with specific azimuthal and radial indices. The optical efficiency exceeds 40% with a radial mode purity of approximately 80%.
