Manipulation of LIPSS orientation on silicon surfaces using orthogonally polarized femtosecond laser double-pulse trains

“…For instance, in holograms and surface color marking, the intensity and color of diffracted light change with the angle between the LIPSS orientation and incident white light. A well-designed LIPSS pattern could transform into a vivid hologram pattern when illuminated by white light [12]. In optical data storage, LIPSS with different orientations could record different types of information [13].…”

Anti-Biofouling Properties of Femtosecond Laser-Induced Submicron Topographies on Elastomeric Surfaces

“…In particular, sub-micron and nanotextures reduce the initial attachment on surfaces, thereby inhibiting the formation of biofilms [9]. Surface texturing is a method to create micro/nanoscale topographies on a surface to alter the physical properties like friction [10], reflectivity [11], wettability [12] and hydrodynamic drag [13]. In solid-liquid contacts, the presence of micro or nanoscale topographies results in either completely wetted Wenzel state (WS) or non-wetted Cassie-Baxter state (CBS).…”

Multi-Angular Colorimetric Responses of Uni- and Omni-Directional Femtosecond Laser-Induced Periodic Surface Structures on Metals

“…In the past few decades, with femtosecond (fs) laser pulse irradiation, several types of quasi-periodic structures can be fabricated on metals [ 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. Among these fs laser-induced periodic surface structures (LIPSSs), regarding structural coloration, low-spatial-frequency LIPSSs (LSFLs) have been popularly investigated because diffraction from LSFLs can be occurred in the entire range of visible wavelengths [ 4 , 5 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ], and the viewing direction of the structural color can be adjusted easily by controlling the period and orientation of LSFLs with the incident angle and the polarization direction of fs laser pulses, respectively [ 7 , 8 , 13 , 15 , 16 , 17 ]. Moreover, LSFLs on metals with high hardness can be used to imprint themselves to the surface of soft metal such as Al [ 18 ], and this is promising for mass production.…”
