Recording and development of Gaussian gratings are analyzed and utilizing these gratings for beam shaping is demonstrated. It is shown that by only use of the holographic process of receiving gratings diffractive shapers for transformation of Gaussian beams to super-Gaussian beams of the fourth degree can be obtained. Holographic shapers were fabricated by interference of natural size laser beams as elements of matrix, which can be used for flat-top beam shaping of laser beams of the natural size.
