DAEJEON, South Korea, June 5, 2018 — A way to measure the shape of laser pulses in ambient air has been developed. In contrast to the existing method for studying waveforms, it does not require a vacuum environment or x-ray pulses. The method (dubbed TIPTOE) can be applied to laser beams of different wavelengths, including UV, visible, or longer. TIPTOE (tunneling ionization with a perturbation for the time-domain observation of an electric field) uses tunnel ionization for the temporal characterization of laser pulse waveforms. Special mirrors divide a laser beam into strong (EF) and weak (ES) laser pulses.
