| Abstract: | Based on the interference of six symmetric beams, we introduce a new way to produce propagation-invariant hollow beams with hexagonal symmetry. The hollow beams have a dark center and hexagonal shape. They can be optical vortices, radially or azimuthally polarized beams. The results of simulation demonstrate the feasibility of this method. |
