The quest for mastering high-power lasers has advanced from initial power scaling to sophisticated beam control. With chirped-pulse amplification catalyzing terawatt and petawatt-scale advancements, the current frontier is refining beam shaping at these extreme powers. We introduce robust monolithic meta-optics, capable of enduring and manipulating high-peak-power laser beams across a wide spectral range, from near-UV to near-IR. These all-glass metasurfaces exhibit a damage threshold at the material's limit, vastly outperforming traditional heterogeneous metasurfaces. We demonstrate the meta-optics robustness with high-peak-power femtosecond pulses. Our nanofabrication protocol allows for precise vertical nanopillars, overcoming previous challenges in tapered sidewalls. We exploit the form birefringence of these nanopillars to induce optical anisotropy in inherently isotropic glass. A geometric perspective underpins our approach to overcoming scaling challenges associated with long-wavelength lasers. Our metasurfaces pave the way for unprecedented control in high-power laser applications.
