Iterative algorithm for the generation of phase masks for spatial laser beam shaping in arbitrary optical systems

International Optical Design Conference, pp. 58

Abstract

Phase-retrieval algorithms are usually limited to the Fourier plane of an optical system. We present a modified iterative Fourier transform algorithm for spatial laser beam shaping in arbitrary optical systems, including systems with optical amplifiers.
