Abstract： By comparing and analyzing the geometric accuracy and wettability of microstructures prepared with different laser pulse widths，the relationship between geometric accuracy and hydrophobicity was established. The results demonstrate that reducing the laser pulse width improves the geometric accuracy of microstructures and enhances their surface hydrophobicity. The picosecondlaser-fabricated microstructures with regular papillae arrays at the bottom region exhibit the optimal water-repellent properties.
