The formation and properties of laser-induced periodic surface structures (LIPSS) were investigated upon fs-laser irradiation of fused silica at different initial substrate temperatures, TS.. For substrate heating between room temperature, TRT, and TS = 1200 °C, a continuous wave CO2 laser was used as the radiation source.. The surface structures generated in the air environment at normal ..
Abstract and Figures.. Laser-induced periodic surface structures (LIPSS) (ripples) with different spatial characteristics have been observed after irradiation of single-crystalline zinc oxide ..
Laser-induced periodic surface structures (LIPSS) are used for the precision surface treatment of 3D components.. However, with LIPSS, the non-normal incident angle between the irradiated laser beam and the specimen surface occurs.. This study investigated LIPSS on four different metals (SUS 304, Ti, Al, and Cu), processed on a tilted surface by an s-polarized femtosecond fiber laser.. A rotated ..
Fig.. 1 (a) shows the SEM image of the ZnO surface after irradiation by 2..5 × 10 5 polarized fs laser pulses.. The pulse energy is 1..7 μJ, and the fluence is approximately 4 J/cm 2.. We can see that a typical laser-induced periodic surface structure (LIPSS) on the crystal surface, the size of aggregated nanoparticles is about 160 nm..
Abstract.. In this work we present the formation of laser induced periodic surface structures (LIPSS) on spin-coated thin films of several model aromatic polymers including poly (ethylene terephthalate), poly (trimethylene terephthalate) and poly carbonate bis-phenol A upon irradiation with femtosecond pulses of 795 and 265 nm at fluences well ..

Self-organized periodic surface structures on ZnO have been observed after multiple linearly polarized femtosecond laser pulse irradiation.. The observed self-organized structures are attributed to the second harmonics in the sample surface excited by the incident laser.. The grating orientation could be adjusted by the laser polarization direction.. We also find that fluences play an important ..
