Abstract
Holographic systems which shape coherent light beams are disclosed. These holographic systems may beam-shaping devices positioned in the path of coherent light beams to shape a coherent light beam into an essentially diffraction noise free coherent light beam of predetermined dimensions that has a continuous light beam profile of distinct intensity zones.
