Paper Abstract

The paper is devoted to designing energy-efficient phase DOEs to generate Gauss-Laguerre modes, ψ0m(r,φ),mM. The DOEs are designed using the Lesem method. For the DOEs operating a plane illuminating beam the optimal DOE aperture radius is calculated. For the DOEs illuminated by the Gaussian beam an extra aperture is not employed, with the radius of an optimal effective radius of the illuminating Gaussian beam calculated in this case. As distinct from the earlier works, the DOE-generated images are being scaled, which results in fairly low root-mean-square deviation and geometric error.
