“…Obviously, the generated structures are perpendicular to the laser polarization. Contrary to these observations, different authors reported on the generation of LSFL on fused silica with an orientation being parallel to the polarization of the laser for both scanning and non-scanning (punctual) cases [12,15,16,36,40]. These parallel structures were never observed in our experiment over the entire parameter range in Figure 2a.…”

“…For the non-scanning case, we also observed these parallel LSFL in a previous study, but never found LSFL with a perpendicular orientation [28]. Xu et al [40] found LSFL on fused silica oriented parallel to the polarization of the laser for both, scanning perpendicularly and parallel to the laser polarization. For perpendicular scanning, we also observed parallel-oriented structures in a previous publication [16].…”

We report on the generation of low spatial frequency laser-induced periodic surface structures along straight lines on fused silica by spatially scanning the laser parallel to its polarization direction. The influence of the applied laser fluence and the scanning speed on the periodic surface structures is investigated. The parameter study shows that periodic structures appear in a limited parameter regime of combined fluence and scan speed with periodicities smaller than the laser wavelength. Most strikingly, we observe a perpendicular orientation of the self-assembled periodic structures to the electrical field of the laser, notably a previously unreported result for this dielectric material. This behavior is explained taking into account calculations of surface plasmon polaritons including a Drude model for free carrier excitation within silica by femtosecond laser irradiation.

“…At 800 cm −1 , the spectrum reveals a peak of the symmetric stretching mode of the Si–O–Si (w 3 ). Finally, peaks observed at 1078 and 1250 cm −1 correspond to the Si–O–Si asymmetric stretching mode (w 4 ) with transversal and longitudinal optical modes, respectively [ 22 ]. After sputtering of a 20 nm thin gold layer, the spectrum is dominated by a broad peak consisting of two maxima at 1337 and 1530 cm −1 .…”

“…Alternative approaches of large-area structuring are therefore based on dot-structures, hierarchical surface structures, and single-spot matrixes [ 20 , 21 , 22 , 23 ]. Furthermore, the application of metallic and semiconducting thin films, deposited on the substrate surface prior to laser structuring, was demonstrated to be advantageous for the formation of LIPSS on large bandgap materials including sapphire [ 24 , 25 ], glasses [ 26 , 27 ], and silicon [ 28 ].…”

Large-Area Fabrication of Laser-Induced Periodic Surface Structures on Fused Silica Using Thin Gold Layers

et al. 2020

Despite intensive research activities in the field of laser-induced periodic surface structures (LIPSS), the large-area nanostructuring of glasses is still a challenging problem, which is mainly caused by the strongly non-linear absorption of the laser radiation by the dielectric material. Therefore, most investigations are limited to single-spot experiments on different types of glasses. Here, we report the homogeneous generation of LIPSS on large-area surfaces of fused silica using thin gold layers and a fs-laser with a wavelength λ = 1025 nm, a pulse duration τ = 300 fs, and a repetition frequency frep = 100 kHz as radiation source. For this purpose, single-spot experiments are performed to study the LIPSS formation process as a function of laser parameters and gold layer thickness. Based on these results, the generation of large-area homogenous LIPSS pattern was investigated by unidirectional scanning of the fs-laser beam across the sample surface using different line spacing. The nanostructures are characterized by a spatial period of about 360 nm and a modulation depth of around 160 nm. Chemical surface analysis by Raman spectroscopy confirms a complete ablation of the gold film by the fs-laser irradiation. The characterization of the functional properties shows an increased transmission of the nanostructured samples accompanied by a noticeable change in the wetting properties, which can be additionally modified within a wide range by silanization. The presented approach enables the reproducible LIPSS-based laser direct-writing of sub-wavelength nanostructures on glasses and thus provides a versatile and flexible tool for novel applications in the fields of optics, microfluidics, and biomaterials.
