Reconstruction algorithm for tunneling ionization with a perturbation for the time-domain observation of an electric-field

Abstract We present a reconstruction algorithm developed for the temporal characterization method called tunneling ionization with a perturbation for the time-domain observation of an electric field (TIPTOE). The reconstruction algorithm considers the high-order contribution of an additional laser p...
