Design and analysis of an elliptical Gaussian laser beam shaping system

Abstract

Geometrical methods have been used to design two-mirror laser beam shaping systems with rectangular symmetry and no central obscuration. These systems are able to transform an input laser beam with an elliptical cross section and a two-axis Gaussian irradiance profile into a rectangularly symmetric output beam with uniform irradiance. The optical design software ZEMAX has been used for modeling and performance analysis of these systems.
