In this paper, we applied this algorithm to the design of diffractive-optical elements for near-field circular SG beam shaping. The algorithm begins with a reasonable number of iterations of basic Gerchberg-Saxton approach until a stable solution is obtained. We found that the robustness of the solution is much stronger.
