Abstract

The invention relates to laser beam apodizators for use in high-energy laser systems with at least one laser or parametric amplification module. The invention also relates to high-energy laser systems and high-energy laser radiation generation methods. It is aimed to form a laser beam of a modified profile in order to achieve the highest possible efficiency of the amplifiers of the laser system and at the same time to ensure low diffraction of the beam when it propagates through the optical elements and in free space inside and outside the laser system. A particular focus is paid to beam propagation through optical elements of a finite diameter in order to minimize the modulation of the beam spatial profile due to diffraction effect on the edges of the active media apertures. A family of functions suitable for laser beam profiles is proposed. The solution allows to increase the efficiency of the laser system of several amplification stages, compared to identical systems in which the Gaussian beam propagates. At the same time, the solution allows to build a laser system of a simpler design and lower price, compared to systems in which the super-Gaussian beam with the flat top is formed.
