“…Vorobyev'sgroup reported a series of studies about this [8,[22][23][24]. LIPSS were induced on the surface of gold plates by a femtosecond laser at a centre wavelength of λ = 800 nm, with a pulse duration of τ = 60 fs and repetition rate of f = 1 kHz.…”

The absorptance of metals is often low within the visible and near-infrared band at room temperature. Increasing the absorption of metals plays a vital role in reducing energy consumption and production cost. After irradiation by 10 ns linearly polarized pulses with fluence close to the zero-probability damage threshold, the surface of 45# steel samples exhibited four kinds of surface structures in the spot area. The samples’ absorptance is improved by 38% when a high-quality laser-induced surface structure (LIPSS) appears at the spot centre. With the increase of the number of pulses, LIPSS begin to melt down, which will decrease the surface absorptance due to the appearance of damage stripes. The relative absorptance of samples was measured by an integrating sphere system. The paper reports detailed experiments to show that LIPSS can improve samples’ absorptance significantly.

“…Ultrafast pulsed laser deposition on ZnO target created variety of nanoforms including nanoparticles and nanorods [2]. Multi-pulse ablation of bulk gold sample results in production of nanostructures caused by combinations of nano-, micro-, and macro-structural surface modifications [3]. Femtosecond laser pulses train that was applied for ablation enables a broad and continuous tunability over the material morphologies ranging from nanoparticle aggregates to epitaxial thin films [4].…”

Electrostriction forces during laser ablation have been studied both theoretically and experimentally. The components of electroctrostriction force for inhomogeneous electromagnetic field near a substrate were proposed to be taken similarly to those in gases within nonresonant spectral region. Nonzero Lorentz force in standing light wave was found to be responsible for different morphology of the nanostructured surface as compared to etching the transient substrate. Our experiments were performed using the femtosecond laser focused on polished glass and Al-coated glass surfaces. The treated surfaces were studied using atomic force microscopy with the spatial resolution of 30 nm. Nanoscale patterning of the etched surface spots was explained in the frames of theoretical modeling. Possible spatial locations of electrostriction force components in the Gauss profile laser beam have been also discussed.

Despite the attractive optical properties of gold nanostructures for emerging applications, the formation of sharp laser-induced periodic gold structures has not been reported. In this study, we experimentally demonstrate the formation of micro- and nanoscale periodic gold grating structures on fused silica substrates using a femtosecond laser. The experimental and calculated results show good agreement, indicating that the gold grating structures were formed by a beat formed in a gold thin film. We also propose that the beat was formed by interference of two surface plasmon polaritons with different periods excited in a gold thin film and calculated their periods.
