“…[49] Later, this effective medium approach was combined also by a Drude model. [51,52] Direct evidence for the involvement of SPPs in the LSFL-I formation was presented in complementary experimental approaches revealing the resonant absorption of radiation in prestructured surface gratings if SPPs can be excited. Garrelie et al subjected a set of 10 nm shallow photolithographically manufactured linear surface gratings on nickel with discrete periods ranging between 440 and 800 nm to normal incident TM (polarization perpendicular to grating ridges) or transverse electric (TE)-polarized (polarization parallel to grating ridges) single 150 fs laser pulses with a center wavelength at = 800 nm.…”

Surface nanostructuring enables the manipulation of many essential surface properties. With the recent rapid advancements in laser technology, a contactless large-area processing at rates of up to m 2 s −1 becomes feasible that allows new industrial applications in medicine, optics, tribology, biology, etc. On the other hand, the last two decades enable extremely successful and intense research in the field of so-called laser-induced periodic surface structures (LIPSS, ripples). Different types of these structures featuring periods of hundreds of nanometers only-far beyond the optical diffraction limit-up to several micrometers are easily manufactured in a single-step process and can be widely controlled by a proper choice of the laser processing conditions. From a theoretical point of view, however, a vivid and very controversial debate emerges, whether LIPSS originate from electromagnetic effects or are caused by matter reorganization. This article aims to close a gap in the available literature on LIPSS by reviewing the currently existent theories of LIPSS along with their numerical implementations and by providing a comparison and critical assessment of these approaches.

“…This control is due to the fact that lasers can deposit a large amount of energy per unit area over a temporal scale shorter than the phonon-electron relaxation time 64 . Recently, fs-laser-induced crystallization in glasses 65 , aspirin 66 and many different kinds of films such as Si [67][68][69][70] , Ti 71 , Ge 72 , and diamond 73 , among others [74][75][76][77][78][79] , has been demonstrated 80 .…”

controlling the structural organization and crystallinity of functional oxides is key to enhancing their performance in technological applications. in this work, we report a strong enhancement of the structural organization and crystallinity of Bi 2 Wo 6 samples synthetized by a microwave-assisted hydrothermal method after exposing them to femtosecond laser irradiation. X-ray diffraction, UVvis and Raman spectroscopies, photoluminescence emissions, energy dispersive spectroscopy, field emission scanning electron microscopy, and transmission electron microscopy were employed to characterize the as-synthetized samples. To complement and rationalize the experimental results, firstprinciples calculations were employed to study the effects of femtosecond laser irradiation. Structural and electronic effects induced by femtosecond laser irradiation enhance the long-range crystallinity while decreasing the free carrier density, as it takes place in the amorphous and liquid states. these effects can be considered a clear cut case of surface-enhanced Raman scattering.Bismuth tungstate, Bi 2 WO 6 (BWO), is an important n-type semiconductor with a narrowband gap energy (E gap ) of 2.8 eV that allows efficient absorption of visible light (λ > 400 nm) and has been widely studied due to its wide range of properties, such as ferroelectricity, piezoelectricity, pyroelectricity, nonlinear dielectric susceptibility, and photoluminescent emissions 1,2 . The multifunctionality of this material has been demonstrated on its photocatalytic activity 3-22 , photocatalytic degradation of drugs 23 , dyes 24-26 alcohols 27 , and phenol 28 , environmental purification, energy conversion 29 , and production of sustainable and combustible compounds 3 . Recently, some works attested this material to be efficient in water splitting for hydrogen generation 30-32 , for shielding against low-energy gamma rays 33 and for CT/IR imaging and photothermal/photodynamic therapy of tumours 34,35 .BWO has an orthorhombic structure and belongs to the Aurivillius family. It is formed by alternating (Bi 2 O 2 ) n 2n+ and perovskite (WO 4 ) n 2n layers 36 , which are composed of (WO 6 ) octahedral layers and (Bi-O-Bi) layers. Their crystal structure can also be described by alternating [Bi 2 O 2 ] 2+ slabs and [WO 4 ] 2− slabs, with oxygen atoms shared between the slabs to create chemical bonds. An important characteristic of this structure is that local environments of both W and Bi cations are highly distorted 37 . The off-centre octahedral distortions are a general feature of the structural chemistry of d 0 metal cations. Each W cation is coordinated with six O atoms to form [WO 6 ] octahedral clusters that are connected to each other by corner-sharing O atoms. The (Bi 2 O 2 ) 2+ layers are sandwiched between (WO 6 ) octahedral layers. From an electronic point of view, BWO presents hybridized valence bands occupied by the Bi 6 s and O 2p states that shift the absorption band edge towards the visible region, with the concomitant appearance of a narrow absorpt...

“…In the case of surface machining of diamond, the use of laser microfabrication technology has been usually limited to the investigation of the periodical sub-micron ripples observed on the sample surface after laser irradiation [115][116][117][118][119][120][121] and to the generation of channel-like microstructures with an average depth of less than half micron [122]. More recently, a collaboration between the groups of Eaton and Jedrkiewicz has shown the possibility to apply this technique combined with the use of ultrashort Bessel beams (BB) for a deep surface ablation of diamond in single pass [123,124], the resulting microstructures offering a great potential for microfluidics or biosensing applications.…”

Diamond has attracted great interest in the quantum optics community thanks to its nitrogen vacancy (NV) center, a naturally occurring impurity that is responsible for the pink coloration of some diamond crystals. The NV spin state with the brighter luminescence yield can be exploited for spin readout, exhibiting millisecond spin coherence times at ambient temperature. In addition, the energy levels of the ground state triplet of the NV are sensitive to external fields. These properties make NVs attractive as a scalable platform for efficient nanoscale resolution sensing based on electron spins and for quantum information systems. Integrated diamond photonics would be beneficial for optical magnetometry, due to the enhanced light-matter interaction and associated collection efficiency provided by waveguides, and for quantum information, by means of the optical linking of NV centers for long-range entanglement. Diamond is also compelling for microfluidic applications due to its outstanding biocompatibility, with sensing functionality provided by NV centers. Furthermore, laser written micrographitic modifications could lead to efficient and compact detectors of high energy radiation in diamond. However, it remains a challenge to fabricate optical waveguides, graphitic lines, NVs and microfluidics in diamond. In this Review, we describe a disruptive laser nanofabrication method based on femtosecond laser writing to realize a 3D micro-nano device toolkit for diamond. Femtosecond laser writing is advantageous compared to other state of the art fabrication technologies due to its versatility in forming diverse micro and nanocomponents in diamond. We describe how high quality buried optical waveguides, low roughness microfluidic channels, and on-demand NVs with excellent spectral properties can be laser formed in single-crystal diamond. We show the first integrated quantum photonic circuit in diamond consisting of an optically addressed NV for quantum information studies. The rapid progress of the field is encouraging but there are several challenges which must be met to realize future quantum technologies in diamond. We elucidate how these hurdles can be overcome using femtosecond laser fabrication, to realize both quantum computing and nanoscale magnetic field sensing devices in synthetic diamond.
