Topological Charge of Optical Vortices

• Broschiertes Buch

Produktbeschreibung

This book is devoted to the consideration of unusual laser beams - vortex or singular beams. It contains many numerical examples, which clearly show how the phase of optical vortices changes during propagation in free space, and the topological charge is preserved.
