ABSTRACT:
Disclosed is an apparatus and method for the modifying the intensity profile of radiant energy beam or reducing its spatial coherence, especially that produced by a laser. The apparatus includes a waveguide having a light reflecting surface including a substructure. The light reflecting surface and substructure reflect incident light causing chaotic scattering which acts to homogenize the intensity profile of the laser beam.
