Paper Abstract

An optical device is proposed and realized for spatial separation into different channels of the Laguerre-Gaussian modes with even and odd mode indices. It was shown that a Gaussian beam diffracted by special computer-synthesized hologram attains in the first order of diffraction a single off-axis optical vortex, which may be represented as superposition of such modes. The proposed separator is able to create 'pure' axial vortex in one output channel and vortices- free beam in another channel. The obtained result is interpreted as a possibility to separate photons with zero and nonzero orbital angular momentum.
