“…As a result, various new laser sources, including ultrafast laser sources (e.g., picosecond, femtosecond, and attosecond laser), ultraviolet laser sources (e.g., excimer laser and harmonics of solid state laser), and low-cost laser sources (e.g., diode laser and fiber laser), become available.

We demonstrate the formation of self-organized nanogratings on a titanium surface under the irradiation of a single-beam femtosecond laser. Self-formed, periodic nanogratings are printed on a titanium surface by varying the average pulse energy, pulse width, and number of laser pulses in each spot. The direction of the nanogratings is perpendicular to the direction of the laser polarization. The nanograting period shows obvious dependence on the average pulse energy, pulse width, and number of laser pulses. The period of the self-organized nanogratings shows an increasing trend with the increase of laser energy and pulse width, and a decreasing trend with an increase of number of applied laser pulses. We qualitatively explain the formation mechanism of the self-organized nanogratings and their dependence on various laser parameters.Subject terms: femtosecond laser; titanium surface; single beam direct laser writing technique, laser-induced periodic surface structure; high-spatial-frequency laserinduced periodic surface structure; low-spatial-frequency laser-induced periodic surface structure.

“…One of the effects of high-power femtosecond laser pulses on metal surface is formation of quasi-periodic surface structures [1][2][3][4]. Modification of surface topology under the influence of laser irradiation leads to changes in physical properties of matter, including the mechanical and optical ones, and therefore surface structuring becomes widely used, for example for creation of "black" and "color" films [5], superhydrophobic surfaces [6,7], etc.…”

Abstract. Under irradiation of the surface of metals with femtosecond laser pulses, periodic surface micro-and nanostructures have been obtained. The dependence of orientation inherent to formed structures on direction of the electric field related with the incident electromagnetic wave and type of polarization of this wave has been studied. Typically these laser-induced structures are perpendicular to the electric field of incident light and have period shorter than the laser wavelength. The structures oriented in parallel to the polarization vector with a longer period have been also revealed. The dependence of surface structure formation on the initial surface defects in metal has been found.

“…Golosov et al studied the ultrafast changes in the optical properties of a Ti surface during the laser ablation process and found that the dependence of the first-harmonic nanograting spacing on the laser fluence was determined by the change in the instantaneous optical characteristics of the material and the saturation of the interband absorption along with the increasing role of intraband transitions [28]. Also, they demonstrated that the periods of LIPSSs could be reduced by carrying out the ablation in water with a larger dielectric constant than air [28,29].…”

Periodic surface structures with periods as small as about one-tenth of the irradiating femtosecond (fs) laser light wavelength were created on the surface of a titanium (Ti) foil by exploiting laser-induced oxidation and third harmonic generation (THG). They were achieved by using 100-fs laser pulses with a repetition rate of 1 kHz and a wavelength ranging from 1.4 to 2.2 μm. It was revealed that an extremely thin TixOy layer was formed on the surface of the Ti foil after irradiating fs laser light with a fluence smaller than the ablation threshold of Ti, leading to a significant enhancement in THG which may exceed the ablation threshold of TixOy. As compared with Ti, the maximum efficacy factor for TixOy appears at a larger normalized wavevector in the direction perpendicular to the polarization of the fs laser light. As a result, the THG-dominated laser ablation of TixOy induces 100-nm periodic structures parallel to the polarization of the fs laser light. The depth of the periodic structures was found to be ~10 nm by atomic force microscopy and the formation of the thin TixOy layer was verified by energy dispersive X-ray spectroscopy.
