Abstract

A beam shaper with 16 levels was designed by Y-G amplitude-phase retrieval and iteration algorithm for converting a given single-mode He-Ne laser beam into a ring-shaped intensity distribution. The ring-shaped intensity distribution is investigated experimentally and compared with the results of the computer simulation when the distance between BOE and CCD is changed. The results show a good conformity.
