Paper Abstract

Multilevel diffractive optical elements for transforming Gaussian beams into rectangular distributions with uniform intensity profile are presented. The effects of different parameters, particularly the phase quantization, on the output field are discussed. It is shown that the interference between the different diffraction orders results in non-uniformity of the output intensity profile. The design is refined to minimize this non-uniformity. The performance of the final design is theoretically analyzed. Actual elements were fabricated and tested and the experimental results are presented. Fabrication considerations are also discussed along with suggestions for improvements.
