“…The generation of femtosecond laser-induced periodic surface structures (fs-LIPSS) is a high-throughput, parallel surface-structuring method with subwavelength or deepsubwavelength resolution [1][2][3][4][5][6][7]. The modified surfaces with LIPSS patterns have important applications in the fields of structural color [8][9][10][11], super-hydrophobicity [12,13], self-cleaning [12,14], and anti-bacterial [15,16], among others.…”

Non-cylindrical vectorial femtosecond lasers are employed to irradiate tungsten surfaces. Compound nanopatterns composed of periodic nanoholes and semi-circular curved ripples are produced by scanning the target relative to the laser beam. The tangential direction of the curved ripples is perpendicular to the local polarization direction of the vectorial femtosecond laser beam. Therefore, the formation mechanism of the curved ripples can be attributed to the interference between the incident femtosecond laser and the laser-induced surface plasmon polaritons (SPPs). We found that, in addition to the curved ripples, periodic nanoholes with an average diameter of 406 nm also appeared on the target surface, and they all tended to appear at the vertexes of the semi-circular curved ripples, i.e., the converging point of SPPs. Further experiments demonstrated that the location of the periodic nanoholes was totally determined by the polarization state of the incident femtosecond laser. Therefore, we deduced that the convergent SPPs induced by the non-cylindrical vectorial femtosecond laser interfered with the incident laser at the convergent point, leading to the generation of periodic nanoholes. The investigations in this work exhibited the important role of manipulating the propagation of SPPs in femtosecond laser surface structuring, which not only diversifies the surface patterns that can be produced by laser-induced periodic surface structuring (LIPSS) but also provides deep insights in the excitation and propagation dynamics of SPPs.

“…Some major drawbacks of the nanosecond and microsecond pulsed lasers during materials processing are the thermal damage of the machined surface and deep heat-affected zone. These disadvantages of laser beam machining in the air can be reduced to some extent by changing the working environment, e. g. vacuum, gasses, liquids [3,4].…”

“…Laser ablation in liquid (LAL) is applicable in engineering, medical and military industry [5]. Furthermore, laser ablation in liquid medium has been proven to be a very promising method for extracting nanoparticles and fabricating hydrides, carbides, and oxides grown by chemical reactions during machining [3,4,6]. Especially significant is the production of titanium nanoparticles, titanium oxides (piezoelectric crystals, fuel cells, sensors) [7] and titanium carbide (cut tool coatings) [8].…”

Titanium grade 2 plates were modified by a pulsed nanosecond laser beam. The aim was to determine the surface properties after the machining process in two different liquid media. The samples were processed in distilled water and paraffin oil. It was found that a surface with half-surface roughness values with a number of cracks was formed in distilled water. The presence of water reduced the size of the heat-affected zone.

“…Maximum redeposited oxides are observed in the case of air treatment while small structures like nano particles are created in Ar ambient. Ali et al [18] studied the development of various kind of features after laser irradiation of metallic targets in air and liquid environments. They observed the enhancement in surface hardness after irradiation in air ambient as compared to liquid ambient.…”

Micro/nano structuring of KrF Excimer laser-irradiated Aluminum (Al) has been correlated with laser-produced structural and mechanical changes. The effect of non-reactive Argon (Ar) and reactive Oxygen (O2) environments on the surface, structural and mechanical characteristics of nano-second pulsed laser-ablated Aluminum (Al) has been revealed. KrF Excimer laser with pulse duration 20 ns, central wavelength of 248 nm and repetition rate of was utilized for this purpose. Exposure of targets has been carried out for 0.86, 1, 1.13 and 1.27 J.cm−2 laser fluences in non-reactive (Ar) and reactive (O2) ambient environments at a pressure of 100 torr. A variety of characteristics of the irradiated targets like the morphology of the surface, chemical composition, crystallinity and nano hardness were investigated by using Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Energy Dispersive X-ray Spectroscopy (EDS), X-ray Diffractometer (XRD), Raman spectroscopy and Nanohardness tester techniques, respectively. The nature (reactive or non-reactive) and pressure of gas played an important role in modification of materials. In this study, a strong correlation is observed between the surface structuring, chemical composition, residual stress variation and the variation in hardness of Al surface after ablation in both ambient (Ar, O2). In the case of reactive environment (O2), the interplay among the deposition of laser energy and species of plasma of ambient gas enhances chemical reactivity, which causes the formation of oxides of aluminum (AlO, Al2O3) with high mechanical strength. That makes it useful in the field of process and aerospace industry as well as in surface engineering.
