Abstract

This paper presents the synthesis of a high efficiency multi-level on-axis Gaussian to flat-top generator designed using an amalgamation of geometrical map transformations and an iterative Fresnel transform algorithm. Initial experiments results show reasonable fidelity in the flat-top area with a conversion efficiency of about 90.5%. Triple harmonic separation filters were designed, and experimental results show high discrimination between the three spectral components.
