Progress and prospects in nonlinear extreme-ultraviolet and X-ray optics and spectroscopy
Free-electron lasers and high-harmonic-generation table-top systems are new sources of extreme-ultraviolet to hard X-ray photons, providing ultrashort pulses that are intense, coherent and tunable. They are enabling a broad range of nonlinear optical and s ...
NATURE PORTFOLIO2023A chip-scale second-harmonic source via self-injection-locked all-optical poling
Tobias Kippenberg, Camille Sophie Brès, Marco Clementi, Junqiu Liu, Edgars Nitiss
Second-harmonic generation allows for coherently bridging distant regions of the optical spectrum, with applications ranging from laser technology to self-referencing of frequency combs. However, accessing the nonlinear response of a medium typically requi ...
2023Nonlinear Frequency Conversion in III-Nitride Doubly Resonant Photonic Crystal Cavities
Nonlinear frequency conversion processes, such as second-harmonic generation (SHG) and spontaneous parametric down-conversion (SPDC), are essential in many applications, including the generation of entangled photons. It's desirable to enhance these process ...
EPFL2023Peculiarities of second harmonic generation with chirped femtosecond pulses at high conversion efficiency
Pierre-Marc Jean Marie Dansette
Frequency doubling of an infrared laser radiation in non-linear optical crystals is a widely used technique to obtain light in the visible range. The second harmonic generation process is influenced by several well-known parameters. In this article we stud ...
ELSEVIER2020Modes interplay controls the second harmonic generation dynamics of plasmonic nanostructures
Olivier Martin, Andrei Kiselev, Gabriel David Bernasconi
A large amount of experimental and theoretical works deals with the second harmonic generation from different plasmonic geometries. Since they often consider relatively long optical pulses, many of these studies are focused on the investigation of a quasi- ...
SPIE2020Eigenmode Analysis in Plasmonics: Application to Second Harmonic Generation and Electron Energy Loss Spectroscopy
Eigenmodes are central to the study of resonant phenomena in all areas of physics.
However, their use in nano-optics seems to have been hindered and delayed for various
reasons. First, due to their small size, the response of nanostructures to a far-field
...
EPFL2019Enhanced second harmonic generation of gold nanostars: optimizing multipolar radiation to improve nonlinear properties
We report a detailed investigation on the second harmonic generation (SHG) emission from single 150 nm diameter non-centrosymmetric gold nanoparticles. Polarization-resolved analysis together with scanning electron microscopy images shows that these nanost ...

Majed Chergui, Marco Grioni, Marcel Drabbels, Frank van Mourik, Alberto Crepaldi, Christopher Alexander Arrell, Gianmarco Gatti, José Javier Pancracio Ojeda Andara, Andrew Daniel Bonnar Clark, Luca Longetti, Silvan Dino Marcos Roth
Harmonium is a vacuum ultraviolet (VUV) photon source built within the Lausanne Centre for Ultrafast Science (LACUS). Utilising high harmonic generation, photons from 20-110 eV are available to conduct steady-state or ultrafast photoelectron and photoion s ...
Swiss Chemical Soc2017Revealing a Mode Interplay That Controls Second-Harmonic Radiation in Gold Nanoantennas
Olivier Martin, Jérémy Butet, Gabriel David Bernasconi, Chen Yan
In this work, we investigate the generation of second- harmonic light by gold nanorods and demonstrate that the collected nonlinear intensity depends upon a phase interplay between di ff erent modes available in the nanostructure. By recording the backward ...
