ABSTRACT
Beam shaping is generally defined as a process to rearrange the intensity and phase of an optical light beam. One of the simplest examples of beam shaping is probably that a plane wave is focused into a spot by a convex lens. The term “beam shape” stands for the intensity profile. The phase profile determines how the intensity profile evolves during propagation. 338 A general beam shaping problem is to find an optical system that operates the incident beam to generate the desired intensity distribution, such as a uniform distribution at a certain area on the target plane (focal region).
