We demonstrate single-shot wave-front measurements of high-peak-power 100-fs laser pulses using the Fresnel phase-retrieval method. The wave fronts are reconstructed from only two intensity distributions at two planes along the optical axis and are measured by means of simple charge-coupled-device cameras. Wave fronts of a terawatt-class laser pulse are measured to be better than 0.36λ, peak to valley, when compared with the measured far-field intensity distributions of the beam.
