Paper Abstract

We propose a new method for transforming an elliptic Gaussian beam, in the near-field, into a circular Gaussian beam in the far field using a very simple diffractive optical element which is a phase slit. We show that a circular Gaussian beam can be transformed into a flat-top profile, a doughnut profile or a ring-shaped profile.
