A long, narrow, relativistic charged particle bunch propagating in plasma is subject to the self-modulation (SM) instability. We show that SM of a proton bunch can be seeded by the wakefields driven by a preceding electron bunch. SM timing reproducibility and control are at the level of a small fraction of the modulation period. With this seeding m...

Plasma wakefield acceleration is a promising technology to reduce the size of particle accelerators. Use of high energy protons to drive wakefields in plasma has been demonstrated during Run 1 of the AWAKE programme at CERN. Protons of energy 400 GeV drove wakefields that accelerated electrons to 2 GeV in under 10 m of plasma. The AWAKE collaborati...

Placental extracellular vesicles (EVs) play an essential role in pregnancy by protecting and transporting diverse biomolecules that aid in fetomaternal communication. However, in preeclampsia, they have also been implicated in contributing to disease progression. Despite their potential clinical value, current technologies cannot provide a rapid an...

Materials platforms that enable controlled isolation and subsequent release of chemical/biological entities are in great demand for a diverse range of practical applications. Current technologies lack good control and efficiency of the release, which is needed to preserve the captured targets of interest. Here, this need is addressed by providing a...

Placental extracellular vesicles (EVs) play an essential role in pregnancy by protecting and transporting diverse biomolecules that aid in fetomaternal communication. However, in preeclampsia, they have also been implicated in contributing to disease progression. Despite their potential clinical value, most current technologies cannot provide a rap...
Article
Laser-Induced Periodic Surface Structures (LIPSS) manufacturing is a convenient laser direct-writing technique for the fabrication of nanostructures with adaptable characteristics on the surface of virtually any material. In this paper, we study the influence of 1D laser wavefront curvature on nanoripples spatial regularity, by irradiating stainles...
Article
A fast and reliable method for the fabrication of polarization modifying devices using femtosecond laser is reported. A setup based on line focusing is used for the generation of LIPSS on stainless steel, processing at different speeds between 0.8 and 2.4 mm/s with constant energy per pulse of 1.4 mJ. SEM and AFM characterizations of the LIPSS show...

The control of the interaction between materials and biological tissues is a key factor to optimize the overall performance of implants and prostheses integrated into the body. With this objective in mind, biomimetic hierarchical one- and two-dimensional surface patterns textured at the micro and nano scales were fabricated on titanium alloys using...

In this paper two kind of sensors based on WO3 sputtered by magnetron sputtering and annealed at 600 °C have been studied. The first kind was processed by two-dimensional direct laser interfering patterning (DLIP) and the second one without any additional treatment. Morphological and structural characterization have shown a hole structure in a peri...

Highly migratory cancer cells often lead to metastasis and recurrence and are responsible for the high mortality rates in many cancers despite aggressive treatment. Recently, the migratory behavior of patient-derived glioblastoma multiforme cells on microtracks has shown potential in predicting the likelihood of recurrence, while at the same time,...
Conference Paper
Laser induced periodic surface structures (LIPSS) can be studied as waveplates due to the birefringence induced by the nanoripples, with easy fabrication since they are fabricated in a one-step process by laser, where LIPSS geometry are defined by the characteristics of the laser and the substrate. The optical properties of these waveplates are def...
Conference Paper
Volume-phase gratings (VPGs) are fabricated in CdSxSe1-x quantum dot doped borosilicate glass at different repetition rates. As the heat accumulation effects caused by the repetition rate lead to changes in the diameter of the modified volume (from 1 to 10 μm), the selective fabrication of thick or thin gratings can be benefitted when the different...
Conference Paper
LIPSS are an emergent method of fabricating functional surfaces. A high repetition rate ultrashort pulsed laser was used to generate LIPSS on metallic surfaces. Different combinations of the processing parameters were tested to study their effect on the period of the LIPSS. Additionally, the influence of the repetition rate (laser frequency) on the...

Surface nanostructuring has received increasing attention in recent years due to the wide range of applications in which it offers advantages. Particularly, Laser-Induced Periodic Surface Structures (LIPSS) have proven useful for surface functionalization. LIPSS are periodic formations generated in most materials when irradiated with linearly polar...
Conference Paper
Since the first refractive index modification of transparent materials was achieved via femtosecond laser micromachining [1], the fabrication of bulk inscribed 3D optical elements has been insistently pursued. This method has been extensively used to generate a variety of photonic devices such as waveguides, couplers or amplifiers, which enabled a...
Article
Volume-phase gratings (VPGs) were fabricated in CdSxSe1−x quantum-dot-doped borosilicate glass at a low repetition rate (800 nm, 140 fs, 1 kHz). The VPGs were designed based on rigorous coupled wave analysis simulations. Results indicate that the inscribed thickness (L) is the key parameter to maximize the diffraction efficiency at order 1. Microsc...
Conference Paper
Birefringence induced by nanoripples generated by laser (Laser Induced Periodic Surface Structures, LIPSS), enables their use as polarization gratings. Their fabrication is simple, as LIPSS geometry is defined by the characteristics of the laser and the substrate in a one-step process. In this work LIPPS generated on stainless steel have been used...

We demonstrate a rapid, accurate, and convenient method for tailoring the optical properties of diamond surfaces by employing laser induced periodic surface structuring (LIPSSs). The characteristics of the fabricated photonic surfaces were adjusted by tuning the laser wavelength, number of impinging pulses, angle of incidence and polarization state...
Conference Paper

Fabricating reflective waveplates using nanostructured surfaces has taken great interest in recent years due to their simple structure: a diffractive grating composed of ripples with subwavelength period. The surface ripples act as an artificial birefringent material: the anisotropy of the surface cor-rugation generates a phase delay between two pe...

ZnO thin film sputtered on alumina substrate is processed by Direct Laser Interference Patterning (DLIP). The heat transfer equation has been simulated for interference patterns with a period of 730 nm and two different fluences (85 mJ/cm² and 165 mJ/cm²). A thermal threshold of 900 K, where crystal modification occurs has been calculated, indicati...

We demonstrate the formation of laser-induced periodic surface structures (LIPSS) in boron-doped diamond (BDD) by irradiation with femtosecond near-IR laser pulses. The results show that the obtained LIPSS are perpendicular to the laser polarization, and the ripple periodicity is on the order of half of the irradiation wavelength. The surface struc...

Ultrafast laser inscription of volume phase gratings with low index contrast and self-images with visibility of 0.96 is demonstrated. It is also demonstrated that phase differences of π/2 for visible light are achievable with only one layer of structures induced in bulk borosilicate glass by direct laser writing. The fabrication method avoids the s...

In the last years the social conscience towards climate change and greenhouse effect, as well as the restrictive laws against gas emissions, have increased. These facts lead into a need for the air quality monitoring on a real-time basis. Nowadays, several specialized measurement systems can be found in the market. However, these are usually too bu...
Conference Paper
In this work the near field diffraction of volume phase gratings fabricated by ultrafast laser inscription in glass is analyzed. It has been found that the increment of the gratings thickness produces widening of the region in which visibility remains above the 75% of its maximum. Result that may increase mechanical tolerance of devices based on Ta...
