“…General methods to form micro-/nanostructures mainly focused on electron-beam lithography [5], nanoprint lithography [6], or chemical methods [7][8][9]. Recently, high spatial frequency laser induced periodic surface structures (HSFL) have been obtained following solid target irradiation with ultrashort laser pulses [10][11][12][13][14][15][16][17]. In many cases, however, the obtained nanostructures are either not well-patterned or not clearly long-range ordered.…”

We demonstrate the coherent linking of periodic nano-ripples formed on the surface of ZnO crystals induced by femtosecond laser pulses. By adjusting the distance between two laser scanning zones, the periodic nano-ripples induced by two separated laser writing processes can be coherently linked and the ZnO nanograting with much longer grooves is therefore produced. The length limitation of this kind of nanograting previously set by the laser focus size is thus overcome. The micro-Raman mapping technique is used to evaluate the quality of coherent linking, and the underlying physics is discussed. The demonstrated scheme is promising for producing large-size self-organized nanogratings induced by femtosecond laser pulses.

“…This new approach holds the potential to explore heretofore inaccessible regimes of laser-matter interactionsuch as the microscopic analysis of laser machining and modification of solids/droplets with infrared (IR) to extreme ultraviolet (XUV) radiation [1,2,61,62] -as well as to study optical processes in nano-photonics and nanoplasmonic structures [63], which can have a thickness of a few atomic layers only. Due to MicPIC's atomic-scale resolution, atomic-level processes are fully accessible, which allows for the quantitative determination of material susceptibilities in terms of microscopic parameters, such as the bulk and surface collision rates.…”

“…Non-relativistic light-matter interaction encompasses a broad spectrum of applications. Lasers can be used for micro-machining and modification of materials, such as metals and dielectrics [1,2]. Whereas micro-machining is of interest for highprecision industrial applications, material modification can be used to write channels into dielectrics for the realization of 3D microfluidic chips [3] or 3D integrated photonic devices for telecommunication [4].…”

Light wave driven electron dynamics in clusters

The dynamics of solid-density nanoplasmas driven by intense lasers takes place in the strongly-coupled plasma regime, where collisions play an important role. The microscopic particle-in-cell method has enabled the complete classical electromagnetic description of these processes. The theoretical foundation of the approach and its relation to existing methods are reviewed. Selected applications to laser cluster processes are presented that have been inaccessible to numerical simulation so far.

“…A decade ago it has been discovered that under certain irradiation conditions ordered sub-wavelength structures with features smaller than 20 nm can be formed in the volume of silica glass [3]. The effect of nanograting formation has attracted considerable interest with proposals of applications ranging from nanofluidics [4,5] to polarization control devices [6].More recently, the self-assembled sub-wavelength nanostructuring have been proposed for fabrication of vortex polarization converters ( Fig. 1) and rewritable polarization multiplexed optical memory [7], where the information encoding is realized by means of two birefringence parameters, i.e.…”

Material processing with ultrafast lasers has attracted considerable interest due to a wide range of applications from laser surgery and integrated optics to optical data storage, 3D micro-and nano-structuring [1,2]. A decade ago it has been discovered that under certain irradiation conditions ordered sub-wavelength structures with features smaller than 20 nm can be formed in the volume of silica glass [3]. The effect of nanograting formation has attracted considerable interest with proposals of applications ranging from nanofluidics [4,5] to polarization control devices [6].More recently, the self-assembled sub-wavelength nanostructuring have been proposed for fabrication of vortex polarization converters ( Fig. 1) and rewritable polarization multiplexed optical memory [7], where the information encoding is realized by means of two birefringence parameters, i.e. the slow axis orientation (4th dimension) and retardance (5th dimension), in addition to three spatial coordinates (Fig.2).A remarkable effect has also been discovered, referred to as quill or calligraphic laser writing, which reveals strong dependence of the material modification, in particular the self-assembled sub-wavelength structures in glass, on orientation of the writing direction relative to direction of the pulse front tilt [8][9][10]. Moreover, evidence of the first order phase transition associated with self-assembled nanostructures formation was revealed and supercooled state of laser damage was observed using pulses with tilted intensity front. More recently it has been demonstrated that the tip of an ultrafast laser quill has a property that is very different from an ordinary quill [11]. Specifically, the modification of glass can be controlled even in stationary conditions by the mutual orientation of light polarization azimuth and the pulse front tilt. Figuratively, the polarization can be used as a sharpening blade for the ultrafast light quill. The demonstrations of self-assembled nano-structuring and employing mutual orientations of beam movement or the light polarization plane and pulse front tilt to control interaction of matter with ultrashort light pulses, open new opportunities in material processing.
