Abstract: (1457 Views)
In this paper, by coherent superposition of two positive and negative radially phase shifted zone plates a novel diffractive element is achieved. It is demonstrated that the element can turn an incident plane wave into a bi-annular optical beam under. In addition, having two manageable axial foci is the other important feature of the element, . As a result this element is able to generate a bottle beam. Finally, the results of the theoretical and experimental works are shown to be well consistent.
