We studied the evolution of femtosecond breakdown in lithographically produced plasmonic nanoparticles with increasing laser intensity. Localized plasmons were generated with 40-fs laser pulses with up to 1.4 × 1012 W/cm2 peak intensity. The damage

Metal nanostructures are central to a wide range of ultrafast plasmonic effects, such as high harmonic generation [1], photoelectron spectroscopy for sub-nm field probing [2], carrier-envelope phase detection [3], plasmon-plasmon coupling [4] etc., w

We report the first observation of strong-field above threshold ionization of Rydberg electron wave packets localized to a gold nanotip. Our experiments represent a step to transferring attosecond techniques from atomic to solid state nanosystems.

We report highly efficient photoelectron emission from gold nanotapers via long-range plasmonic nanofocusing. This new source of remotely-generated few-femtosecond electron pulses is implemented in a point-projection-microscope and first steps toward

We report the first observation of atomic-like above-threshold-ionization from a gold nanotip by exciting long-lived Rydberg electron wave packets. These results transfer high harmonic generation and attosecond gating techniques from atoms to solid s

Image potential states are well established surface states of metallic films [1]. For a single metallic nanostructure these surface states can be localized in the near-field arising from illumination by a strong laser field. Thus single metallic nano

We report photoelectron emission from the apex of a sharp gold nanotaper illuminated via grating coupling at a distance of 50 μm from the emission site with few-cycle near-infrared laser pulses. We find a fifty-fold increase in electron yield over t

Femtosecond laser-induced damage threshold (LIDT) measurements for different optical components are well studied for a set of laser pulse repetition rates spanning the range between 1 Hz and 1 kHz. Recent years saw the advent of high-repetition-rate

Improving the laser-induced damage threshold of optical components is a basic endeavor in femtosecond technology. By testing more than 30 different femtosecond mirrors with 42 fs laser pulses at 1 kHz repetition rate, we found that a combination of h

Aberration correction using Reference Conjugated Hologram (RCH) method is investigated. However we use it not for a single but for a number of reconstructed object planes in Digital Holographic Microscopy (DHM). We build an off-axis DHM for testing t
