Holographic information is obtained from the interference of the transmitted primary beam with the fields scattered from the modified or unknown target regions. A specialized iterative phase retrieval is used to incorporate the holographic nature of the approach and to accelerate and improve convergence. The published data contain all data shown in the figures of the paper "Ultrafast imaging of laser-induced modifications in planar targets via single-shot in-line holography".
