Paper Abstract

E-beam lithography was used to fabricate an 8-channel phase DOE capable of selecting angular harmonics with the number +/- 1, +/- 2, +/- 3, and +/- 4. It has experimentally been demonstrated that this filter can successfully extract angular harmonics from laser beams composed of Gauss-Laguerre modes.
