Paper Abstract

A diffractive optical element (DOE) is designed with a new algorithm for transforming a rotationally symmetrical Gaussian beam into a nearly diffraction-limited flat-top by Fourier transformation system. The simulating results indicate that size of the shaped spot is only twice more than one of the diffraction limited spot, the diffraction efficiency is about 71.38$ and the edge of the uniform area is dramatically sharper than the one without DOE.
