“…San-Blas et al demonstrated experimentally that the (de-)focusing of a pulsed fs-laser beam by a cylindrical lens has an impact on the regularity of the LIPSS formed on steel surfaces [50]. The authors observed the best regularity for plane wavefronts of the focused laser beam, i.e., either in the focal position (Figure 4c) or when working far away from it.…”

Laser-induced periodic surface structures (LIPSS) are a simple and robust route for the nanostructuring of solids that can create various surface functionalities featuring applications in optics, medicine, tribology, energy technologies, etc. While the current laser technologies already allow surface processing rates at the level of m2/min, industrial applications of LIPSS are sometimes hampered by the complex interplay between the nanoscale surface topography and the specific surface chemistry, as well as by limitations in controlling the processing of LIPSS and in the long-term stability of the created surface functions. This Perspective article aims to identify some open questions about LIPSS, discusses the pending technological limitations, and sketches the current state of theoretical modelling. Hereby, we intend to stimulate further research and developments in the field of LIPSS for overcoming these limitations and for supporting the transfer of the LIPSS technology into industry.

“…A Ti:Sapphire laser emitting 120 fs pulses with a central wavelength 𝜆 = 800 nm at a repetition rate of 1 kHz was used for the generation of the nanostructures [18]. In this contribution, the laser beam was focused onto the surface of the sample through a cylindrical lens of focal length 𝑓 = 100 mm (see Fig.…”

“…The fabricated sample was processed under irradiation conditions of 𝐸 = 0.55 mJ pulse energy and 𝑣 = 0.625 mm/s displacement speed. The surface of the stainless steel was positioned along the 𝑍-axis so that the processing took place at the beam waist of the laser beam, in order to achieve higher regularity in the resulting nanostructures [18]. The sample was translated 30 mm under irradiation from the laser beam.…”

“…In Ref. [ 15 ], the physical origin of regularity was linked to a decay length of excited surface plasmon polaritons (SPP), and the dispersion of the LIPSS orientation angle (DLOA) proposed in that study is now often used as a regularity criterion [ 19 , 20 , 21 , 22 , 23 ].…”

A systematic experimental study was performed to determine laser irradiation conditions for the large-area fabrication of highly regular laser-induced periodic surface structures (HR-LIPSS) on a 220 nm thick Mo film deposited on fused silica. The LIPSS were fabricated by scanning a linearly polarized, spatially Gaussian laser beam at 1030 nm wavelength and 1.4 ps pulse duration over the sample surface at 1 kHz repetition rate. Scanning electron microscope images of the produced structures were analyzed using the criterion of the dispersion of the LIPSS orientation angle (DLOA). Favorable conditions, in terms of laser fluence and beam scanning overlaps, were identified for achieving DLOA values <10∘. To gain insight into the material behavior under these irradiation conditions, a theoretical analysis of the film heating was performed, and surface plasmon polariton excitation is discussed. A possible effect of the film dewetting from the dielectric substrate is deliberated.
