Less is more - enhancement of second-harmonic generation from metasurfaces by reduced nanoparticle density
Robert Czaplicki, Antti Kiviniemi, Mikko J. Huttunen +7
We investigate optical second-harmonic generation (SHG) from metasurfaces where noncentrosymmetric V-shaped gold nanoparticles are ordered into regular array configurations. In con…
Femtosecond phase-transition in hard x-ray excited bismuth
M. Makita, I. Vartiainen, I. Mohacs +19
The evolution of the bismuth crystal structure upon excitation of its A phonon has been intensely studied with short pulse optical lasers. Here we present the first-time obs…
Laboratory demonstration of a mid-infrared AGPM vector vortex coronagraph
Christian Delacroix, Olivier Absil, Pontus Forsberg +9
Coronagraphy is a powerful technique to achieve high contrast imaging and hence to image faint companions around bright targets. Various concepts have been used in the visible and…
