Paper Abstract

Systems for the reshaping of laser beams are widely used today. Most applications can be found in the fields of technical illuminations or material processing. Beam shaping is typically done using one or more diffractive or refractive surfaces. The fabrication of these surfaces is quite expensive in the most cases, especially if merely prototypes or a small number of systems are required. The authors will show ideas how to design beam shaping systems for the reshaping of circular Gaussian beams into circular Top Hats using standard spherical catalog lenses. These ideas allow the development of low cost beam shaping systems. The required elements can be ordered for less than $100 in catalogs typically. Concepts for the selection of lenses from catalogs as well as optimization strategies will be explained. Theoretical design examples will be discussed and simulation results will be compared with measurement data.
