The role of focused laser plasmonics in shaping SERS spectra of molecules on nanostructured surfaces
Fran Nekvapil, Cosmin Farcău
The dependence of surface-enhanced Raman scattering (SERS) spectra on the precise axial position of the laser focus relative to a solid nanostructured substrate has received little…
Linear Arrays of Metal-Coated Microspheres: a Polarization-Sensitive Hybrid Colloidal Plasmonic-Photonic Crystal
Cosmin Farcău
Colloidal plasmonic-photonic crystals represent a class of hybrid materials composed of a dielectric colloidal spheres photonic lattice and a metal plasmonic film. In this work, th…
Metal-coated microsphere monolayers as surface plasmon resonance sensors operating in both transmission and reflection modes
Cosmin Farcău
Metal-coated microsphere monolayers (MCM) are a class of plasmonic crystals consisting of noble metal films over arrays of self-assembled colloidal microspheres. Despite their ease…
Metasurface Engineering with Tantalum Pentoxide-Coated Microspheres: Tailoring Optical Resonances and Enhancing Local Density of States
Alexandra Fălamaş, Ana Maria M. Gherman, Renaud Vallée +1
Hexagonally-packed polystyrene microsphere monolayers coated with tantalum pentoxide (TaO) form scalable dielectric metasurfaces that support tunable photonic resonances an…
Efficient Coherent XUV Generation and Manipulation in Microfluidic Glass Devices
Anna Gabriella Ciriolo, Rebeca Martínez Vázquez, Gabriele Crippa +12
The development of compact and bright XUV and soft X-ray sources based on high-order harmonic generation is boosting advances towards understanding the behavior of matter with extr…
High-harmonic generation in a strongly overdriven regime
B. Major, K. Kovács, E. Svirplys +6
High-harmonic generation (HHG) normally requires a careful adjustment of the driving laser intensity (typically W/cm) and gas medium parameters to enable go…
Compact intense extreme-ultraviolet source
Balázs Major, Omair Ghafur, Katalin Kovács +4
High-intensity laser pulses covering the ultraviolet to terahertz spectral regions are nowadays routinely generated in a large number of laboratories. In contrast, intense extreme-…
Propagation-assisted generation of intense few-femtosecond high-harmonic pulses
B. Major, M. Kretschmar, O. Ghafur +11
The ongoing development of intense high-harmonic generation (HHG) sources has recently enabled highly nonlinear ionization of atoms by the absorption of at least 10 extreme-ultravi…
The effect of plasma-core induced self-guiding on phase matching of high-order harmonic generation in gases
Balázs Major, Katalin Kovács, Valer Tosa +3
In this work we numerically study a self-guiding process in which ionization plays a dominant role and analyze its effect on high-order harmonic generation (HHG) in gases. Although…
Scale-invariant nonlinear optics in gases
C. M. Heyl, H. Coudert-Alteirac, M. Miranda +8
Nonlinear optical methods are becoming ubiquitous in many areas of modern photonics. They are, however, often limited to a certain range of input parameters, such as pulse energy a…
Genetic optimization of attosecond pulse generation in light-field synthesizers
E. Balogh, B. Bódi, V. Tosa +3
We demonstrate control over attosecond pulse generation and shaping by numerically optimizing the synthesis of few-cycle to sub-cycle driver waveforms. The optical waveform synthes…
Quasi-phase-matching high-harmonic radiation using chirped THz pulses
Katalin Kovács, Emeric Balogh, János Hebling +2
High-order harmonic generation in the presence of a chirped THz pulse is investigated numerically with a complete 3D non-adiabatic model. The assisting THz pulse illuminates the HH…
Influence of generalized focusing of few-cycle Gaussian pulses in attosecond pulse generation
Ebrahim Karimi, Carlo Altucci, Valer Tosa +2
In contrast to the case of quasi-monochromatic waves, a focused optical pulse in the few-cycle limit may exhibit two independent curved wavefronts, associated with phase and group…
