Popis: A new modernization of the Gerchberg-Saxton (GS) iterative algorithm has been suggested with reference to the task of focusing a coherent monochromatic beam into a preset frequency-plane domain with a given intensity distribution. The modernization proposed permits computation of the transmittance function, within a diffraction approximation, of the optical element focusing into a preset domain, with an error essentially less than that of the standard variant of the GS algorithm.
