High‐Quality Femtosecond Laser Surface Micro/Nano‐Structuring Assisted by A Thin Frost Layer (Adv. Mater. Interfaces 9/2023)

Laser Surface Micro/Nano-Structuring A thin frost layer is preliminarily formed by condensation of ambient water vapor onto the cooled workpiece surface with a temperature below freezing point. When a femtosecond laser is focused onto the frost-covered surface, the local frost layer around the laser spot melts into water film, enabling high-quality surface micro/nano-structures on both plane and curved surfaces at high laser fluences.
