“…In this work, we present experimental results showing that regular oxidative LIPSSs, which have not been previously observed in the range of low-temperature (below the melting point) processes on thin titanium films, can be obtained under the action of nanosecond laser pulses. Recording, in this case, was conducted using the method of direct laser thermochemical writing on thin metal films (for instance, on Ti [21,[23][24][25][26][27], Sn [28], V [29], Zr [29], etc. ), in which the image is created by direct oxidation of the original film under local laser heating until the formation of a contrasting transparent oxide layer (for further information about this method, see [23]).…”

Laser-induced periodic surface structures (LIPSSs) spontaneously appearing on the laser-treated (melted or evaporated) surfaces of bulk solid materials seem to be a well-studied phenomenon. Peculiarities of oxidative mechanisms of LIPSS formation on thin films though are far less clear. In this work, the appearance of oxidative LIPSSs on thin titanium films was demonstrated under the action of commercially available nanosecond-pulsed Yb-fiber laser. The temperature and energy regimes favoring their formation were revealed, and their geometric characteristics were determined. The period of these LIPSSs was found to be about 0.7 λ, while the modulation depth varied between 70 and 110 nm, with high stability and reproducibility. It was shown that LIPSS orientation is rather easily manageable in the regimes of our interest, which could provide a way of controlling their properties.
