“…Our calculations indicate, however, that the origin of these waves is mixed depending on the structure geometry and, therefore, on Mie scattering or previously mentioned quasi-cylindrical waves on the surface, optical properties of the media (metal or glass), and, where the conditions are satisfied, additional contribution of surface plasmon wave for metal surfaces, as proposed in Refs. [12,19]. Similar geometrical effects from more complexed structures such as microtriangles and microsquares with imprinted patterns oriented both perpendicular and parallel to laser polarization were observed experimentally [14].…”

“…These features have consequences in multipulse irradiation, where evolving surface topography or deformation centers influence the feedback process [17]. The introduction of artificial supra-wavelength scattering objects on the surface, such as elongated nanoridges and nanoslits, affects not only the dominant pattern configuration, but also results in more regular planar wavefront of the scattered waves [12,13,19]. Our calculations indicate, however, that the origin of these waves is mixed depending on the structure geometry and, therefore, on Mie scattering or previously mentioned quasi-cylindrical waves on the surface, optical properties of the media (metal or glass), and, where the conditions are satisfied, additional contribution of surface plasmon wave for metal surfaces, as proposed in Refs.…”

“…The energy absorption maps on the surfaces are particularly required to understand laser interac-tion with matter, because the patterns of maximum absorbed energy define precisely the thermoaffected zones, where the material modification such as ablation is likely to take place after the energy deposition [12][13][14][15][16][17][18][19]. This way, the laseraffected surface can be efficiently treated pulse by pulse.…”

This paper deals with a numerical investigation of the energy deposition induced by ultrafast laser interaction with nanostructures. We calculate and analyze the intensity near-field reactive and radiative patterns resulted from the interference of the incident light with light scattered by individual subwavelength holes and bumps on the surface of metallic and dielectric materials. The role of light polarization, optical material properties, collective effects and nature of the imperfections in localized energy absorption is elucidated. The results open new perspectives in precise light manipulation by surface inhomogeneities and well-controlled surface nanostructuring by ultrashort laser.

“…Under femtosecond laser irradiation, a large number of free electrons are excited, resulting in a significant change in the dielectric constant, according to the Drude model. The SPP wavelength and LSFL period can be calculated based on the dielectric constant in the excited state, which agrees well with the experimental results for semiconductors 42,51,52 . The LSFL periods induced by femtosecond laser pulses on semiconductors and metals are always smaller than the SPP wavelengths.…”

Over the past two decades, femtosecond laser-induced periodic structures (femtosecond-LIPSs) have become ubiquitous in a variety of materials, including metals, semiconductors, dielectrics, and polymers. Femtosecond-LIPSs have become a useful laser processing method, with broad prospects in adjusting material properties such as structural color, data storage, light absorption, and luminescence. This review discusses the formation mechanism of LIPSs, specifically the LIPS formation processes based on the pump-probe imaging method. The pulse shaping of a femtosecond laser in terms of the time/frequency, polarization, and spatial distribution is an efficient method for fabricating high-quality LIPSs. Various LIPS applications are also briefly introduced. The last part of this paper discusses the LIPS formation mechanism, as well as the high-efficiency and high-quality processing of LIPSs using shaped ultrafast lasers and their applications.

“…Femtosecond laser-induced periodic surface structures (LIPSS) have been studied extensively for many types of materials, such as metals, semiconductors, dielectric solids, and thin films [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Owing to its versatility and flexibility, femtosecond LIPSS has become an efficient processing technique for fabricating functional devices, for structural color, absorption and luminescence enhancement, and large-area gratings [15][16][17][18][19].…”

By using infrared to ultraviolet (IR-UV) femtosecond laser directing, periodic nanostructures were efficiently fabricated on an F-doped tin oxide (FTO) film with a thickness of 650 nm. The morphology of the nanostructures and duty cycle were studied in detail by changing the laser fluence and scanning speed, where three lasers with central wavelengths of 343, 515, and 1,030 nm were used in the experiments. Under the 515 nm laser irradiation with scanning speed of 0.01 mm/s and laser fluence of 23 mJ/cm2, the periods Λ is 172 nm, the ablated nanogroove with width w2 is 52 nm, the birefringence Δn reached a maximum of 0.21, and the phase retardance was up to 135 nm. The morphology of the nanostructures and the birefringence effects of the FTO film prepared by a femtosecond laser at wavelengths of 1,030 and 343 nm were also studied, where the phase retardance of the nanostructured FTO film was much lesser than for the 515 nm laser because the thickness of the nanoripples layer, and, thus, the duty cycle of periodic nanoripples was smaller. Finally, a large-area FTO film with periodic nanostructures was fabricated efficiently by direct laser writing using a 515 nm fs laser beam focused via a cylindrical lens, and demonstrated the characteristics of a quarter-wave plate for 532 nm light.
