Vortex-bearing array of singular beams with very high orbital angular momentum

Opt Lett. 2006 Sep 1;31(17):2523-5. doi: 10.1364/ol.31.002523.

Abstract

We consider theoretically and experimentally an array of singular beams whose axes lie on the surface of a hyperboloid of revolution. We show that such a singular array can carry a very high orbital angular momentum. Experimental results demonstrate a way of generating such singular arrays.
