A system and/or method for spatial beam shaping of an incident laser beam. The system and/or method includes a laser beam source for providing the incident laser beam and a Bragg grating (BG) coupled to receive the incident laser beam from the laser beam source. The BG has a thickness that is not less than a cross sectional size of the incident laser beam in the plane of beam diffraction. The BG produces a diffracted beam from the incident laser beam and the various depths within the BG include a distribution of diffraction efficiency density for spatially shaping the incident laser beam into the diffracted beam.
