Large aperture metasurfaces for the next generation of high-energy lasers

High-energy laser systems envisioned as future IFE laser drivers will use hundreds to thousands of 10 cm (and above) aperture optical components for amplifying, filtering, carrying, sometimes compressing and/or frequency-converting, and focusing laser beams. These optical components will need to combine low losses with high wavefront quality and high damage resistance over millions of shots. Current ICF laser drivers and UHI laser systems have taken advantage of diffraction gratings either in transmission or in reflection bringing the technology to the required performance. We will show the strong potential of silica-based metasurfaces for manipulating high-energy laser beams and will outline some potential applications of these new structures for future IFE laser drivers.
