Abstract: The task of transforming a given intensity distribution into a different, desired intensity distribution can be achieved either by diffractive optical elements or by beam shaping. The most essential difference between these two approaches is that with diffractive optics, the output amplitude results from a superposition of all contributions of the input plane, while in beam shaping there is a one-to-one correspondence between the Poynting-vectors in both planes. Consequently, beam shaping does not require temporal coherence. Applications of beam shaping are typically in the area of high power lasers, due to loss at the focusing lens. In the contribution, different techniques for designing beam shaping elements are discussed and an extention to analytic methods will be presented.
