Abstract
Compressing high-energy laser pulses to a single cycle will break the current limitation of super-scale projects and facilitate future Exawatt lasers. However, the lack of ultra-broadband gratings capable of supporting single-cycle pulse stretching and compression is a core problem that cannot be overcome. Recently, we solved this problem and developed gratings with the broadest bandwidth (broader than 400 nm) that can support near-single-cycle laser pulses (about 4 fs). A 200 mm (Length) ultra-broadband grating is being fabricated supporting a single-cycle terawatt-level prototype. Meanwhile, the 1600 mm (Length) fabrication campaign is underway and will be completed in 2024–2025 at SIOM, facilitating the single-cycle Exawatt lasers.
