Paper Abstract

Recording and development of Gaussian gratings are analyzed, and utilizing these gratings for beam shaping is demonstrated. It is shown that by using only holographic recordings of gratings, diffractive shapers for transformation of Gaussian beams to super-Gaussian beams of the fourth degree, and more as well, can be obtained. Holographic shapers are fabricated by interference of natural-size laser beams as elements of a matrix, which can be used for flat-top beam shaping of laser beams of natural size. If appropriate shaping of a beam is demanded, the necessary shaper can be found among a number of realizations in the matrix, or in a set of such matrices, without any calculations or preliminary measurements.
