Shaping optical vortex beams with topological charge

Not Accessible

Your library or personal account may give you access

Abstract

We show that it is possible to shape the spatial intensity profile of vortex beams by spatially arranging topological charges on a phase mask. In our experiments, we generated vortex beams shaped as straight lines, corners and triangles.
