Abstract

Ramsey-like techniques, based on the coherent excitation of a sample by delayed and phase-correlated pulses, arepromisingtoolsforhigh-precisionspectroscopictestsofQEDintheextreme-ultraviolet(xuv)spectralregion, but currently suffer experimental limitations related to long acquisition times and critical stability issues. Here we propose a random subsampling approach to Ramsey spectroscopy that, by allowing experimentalists to reach a given spectral resolution goal in a fraction of the usual acquisition time, leads to substantial improvements in high-resolution spectroscopy and may open the way to a widespread application of Ramsey-like techniques to precision measurements in the xuv spectral region.
