A new method was used to design diffractive optical elements (DOE) based on improved iterative algorithm. This method shortened the computing time tremendously and the aberration factor of the design was about 8.4%. A DOE with 16 steps construction and quantized phase was fabricated with ion beam moving etching technology. Test results showed that the aberration factor was about 19% which proved the feasibility of the algorithm. The machining error in DOE was analyzed.
