Single freeform surface design for prescribed input wavefront and target irradiance
Christoph Bösel, Herbert Gross
In beam shaping applications, the minimization of the number of necessary optical elements for the beam shaping process can benefit the compactness of the optical system and reduce…

Ray mapping approach in double freeform surface design for collimated beam shaping beyond the paraxial approximation
Christoph Bösel, Norman G. Worku, Herbert Gross
Numerous applications require the simultaneous redistribution of the irradiance and phase of a laser beam. The beam shape is thereby determined by the respective application. An el…
