Abstract

The continuous phase plate with a large wavefront gradient is used as the far-field beam shaping element in some highpower laser physics experiments. During the fabrication of continuous phase plate and before the actual use, it is necessary to measurement its wavefront to judge the fabrication quality and whether the wavefront distribution meets the requirement of use. By constructing a novel amplitude replacement phase retrieval algorithm with variable weighting factor, fast and high precision reconstruction of CPP with large wavefront gradient can be achieved. The proposed method is validated by numerical simulation and experiment.
