Femtosecond Laser-Induced Periodic Surface Structures on Tungsten- femtosecond laser-induced periodic surface structures revisited a comparative study on zno ,We generate periodic surface structures on tungsten at various laser wavelengths, despite that the table values of the dielectric constants indicate the absence of surface plasmons, a wave necessary for forming periodic structures on metals. Femtosecond laser-induced periodic surface structures ...Laser-induced periodic surface structures (LIPSS) (ripples) with different spatial characteristics have been observed after irradiation of single-crystalline zinc oxide surfaces with multiple linearly polarized femtosecond pulses (150-200 fs, 800 nm) in air. For normal incident laser radiation, low spatial frequency LIPSS (LSFL) with a period (630-730 nm) close to the wavelength and an ...

The column “Type” specifies if a material is a metal M, a semiconductor S or a dielectric D. In the third column, the range of the pulse duration τ is indicated. Here, “ns” and “fs” denote nanosecond and femtosecond respectively. - "Modeling laser-induced periodic surface structures: an electromagnetic approach"

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, …
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 ...
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 ...

4. Conclusion. Single- and 10-pulse laser-induced surface damage characteristics of fused silica were comprehensively investigated using a 40-fs Ti: sapphire laser system operating at a central wavelength of 800 nm. The sample displayed damage crater with single-pulse irradiation, and a raised rim was formed around the crater.
Self-organized periodic structures have been observed on the surface of the ablation craters of Ge-S based chalcogenide glass produced after irradiation by a focused beam of a femtosecond Ti:sapphire laser (1 kHz, 34 fs, 806 nm). Scanning electron microscopy and atomic force microscopy images of irradiated spots show a periodic structure of ripples with a spatial period of 720 nm (close to the ...
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 role in the formation of self-organized nanostructures.
