The simultaneous nanometer spatial confinement and femtosecond temporal control of an
optical excitation has been a long-standing challenge in optics. Previous approaches using …

Broadband excitation of plasmons allows control of light-matter interaction with nanometric
precision at femtosecond timescales. Research in the field has spiked in the past decade in …

We propose and analyze a scheme for ultrafast spectroscopy with nanometer spatial and
femtosecond temporal resolution. The interaction of polarization-shaped laser pulses with a …

We demonstrate adiabatic nanofocusing of few-cycle light pulses using ultrasharp and
ultrasmooth single-crystalline gold tapers. We show that the grating-induced launching of …

The local enhancement of few-cycle laser pulses by plasmonic nanostructures opens up for
spatiotemporal control of optical interactions on a nanometer and few-femtosecond scale …

We present a review on the advances of pulse control and ultrafast coherent excitation of
both plasmonic nanoantennas and individual molecular systems, primarily based on the …

The efficiency of plasmonic nanostructures as optical antennas to concentrate optical fields
to the nanoscale has been limited by intrinsically short dephasing times and small …

We present a technique to characterize ultrashort pulses at the focal plane of a high
numerical aperture objective with unprecedented spatial resolution, by performing a FROG …

Experimental methods for ultrafast microscopy are advancing rapidly. Promising methods
combine ultrafast laser excitation with electron-based imaging or rely on super-resolution …
