Refractive Gauss-to-Tophat Beam Shapers Improve Structure Quality and Speed in Micro-machining

Not Accessible

Your library or personal account may give you access

Abstract

The transformation principle of a Gaussian beam into a homogeneous top-hat profile by means of free-form refractive micro-optics is reviewed. Various flat-top profiles achieved with different laser sources as well as micro-machining results are demonstrated.
