Multi-beam vortex generation induced by the non-linear optical anisotropy of graphene [PDF]

open access: yesEPJ Web of Conferences, 2022
We analyse the high harmonic emission from single-layer graphene driven by infrared vector beams. We demonstrate that graphene’s anisotropy offers a privileged scenario to explore non-trivial light spin-orbit couplings, which substantially extends the ...

Ultraestable spatiotemporal characterization of optical vortices in the visible and near infrared [PDF]

open access: yesEPJ Web of Conferences, 2022
We show the versatility of the bulk lateral shearing interferometer characterizing complex spatiotemporal structures in different spectral ranges. Specifically, we have characterized constant and timevarying optical vortices in the visible and near ...

Overlapping Limitations for ps-Pulsed LIFT Printing of High Viscosity Metallic Pastes

open access: yesMetals, 2020
Laser-induced forward transfer (LIFT) technique has been used for printing a high viscosity (250 Pa·s) commercial silver paste with micron-size particles (1−4 µm).

Fourier-limited attosecond pulse generation with magnetically pumped high-order harmonic generation [PDF]

open access: yesEPJ Web of Conferences, 2022
After more than two decades of attosecond physics, the generation and control of the shortest laser pulses available remains as a complex task. One of the main limitations of reducing the temporal duration of attosecond pulses emitted from high-order ...

Machine-learning applied to the simulation of high harmonic generation driven by structured laser beams [PDF]

open access: yesEPJ Web of Conferences, 2023
High harmonic generation (HHG) is one of the richest processes in strong-field physics. It allows to up-convert laser light from the infrared domain into the extreme-ultraviolet or even soft x-rays, that can be synthesized into laser pulses as short as ...

Stochastic homogenization of the laser intensity to improve the irradiation uniformity of capsules directly driven by thousands laser beams [PDF]

open access: yes, 2011
Illumination uniformity of a spherical capsule directly driven by laser beams has been assessed numerically. Laser facilities characterized by ND = 12, 20, 24, 32, 48 and 60 directions of irradiation with associated a single laser beam or a bundle of NB ...

Visible short-pulses generation by nonlinear propagation of necklace beams in capillaries [PDF]

open access: yesEPJ Web of Conferences, 2020
We study numerically the propagation of necklace beams through a gas-filled capillary. Ultra-short pulses in the visible (VIS) region can be obtained due to the spectral broadening of these necklace beams.

Pulse self-compression down to the sub-cycle regime in hollow capillary fibers with decreasing pressure gradients [PDF]

open access: yesEPJ Web of Conferences, 2022
We theoretically demonstrate an enhancement in the generation of clean, near-infrared sub-cycle laser pulses by soliton self-compression in gas-filled hollow capillary fibers using decreasing pressure gradients. Furthermore, we identify the optimal input
