Interferometric Method Measures Interactions at Zeptosecond Speed
NATHAN, Australia, Dec. 16, 2022 — According to researchers at the Australian Attosecond Science Facility and the Centre for Quantum Dynamics of Griffith University, building an interferometer in the extreme ultraviolet (EUV) region is challenging for two reasons. First, it is itself a challenge to control the delay of the EUV pulses precisely between the two arms with subcycle precision. Second, the researchers said, necessary highly reflective EUV optics are not yet developed. Overcoming these barriers, the
