Single‐Pulse Nanomorphology Governs Laser‐Induced Periodic Surface Structure Formation on Metals

open access: yesLaser &Photonics Reviews, Volume 20, Issue 2, 22 January 2026.
Ultrashort pulse ablation enables generation of self‐organized periodic structures, where evolving nanomorphology controls pulse‐to‐pulse feedback. In noble metals, nanospikes form after the first pulse and localize surface waves, preventing periodic field distributions and thus suppressing their formation.
