Spatiotemporal characterization of ultrashort optical vortex pulses
Miguel Miranda, Marija Kotur, Piotr Rudawski +4
Generation of few-cycle optical vortex pulses is challenging due to the large spectral bandwidths, as most vortex generation techniques are designed for monochromatic light. In thi…

Photoemission electron microscopy of localized surface plasmons in silver nanostructures at telecommunication wavelengths
Erik Mårsell, Esben W. Larsen, Cord L. Arnold +3
We image the field enhancement at Ag nanostructures using femtosecond laser pulses with a center wavelength of 1.55 micrometer. Imaging is based on non-linear photoemission observe…
