The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Recently two emerging areas of research, attosecond and nanoscale physics, have started
to come together. Attosecond physics deals with phenomena occurring when ultrashort laser …

We present the development of the first ultrafast transmission electron microscope (UTEM)
driven by localized photoemission from a field emitter cathode. We describe the …

In the past 20 years, we have reached a broad understanding of many light-driven
phenomena in nanoscale systems. The temporal dynamics of the excited states are instead …

Plasmonics is a rapidly growing field spanning research and applications across chemistry,
physics, optics, energy harvesting, and medicine. Ultrafast photoemission electron …

Attosecond science is based on electron dynamics driven by a strong optical electric field
and has evolved beyond its original scope in gas-phase atomic and molecular physics to …

We experimentally and theoretically visualize the propagation of short-range surface
plasmon polaritons using atomically flat single-crystalline gold platelets on silicon …

Progress in ultrafast electron microscopy relies on the development of efficient laser-driven
electron sources delivering femtosecond electron pulses to the sample. In particular, recent …

We use subcycle time-resolved photoemission microscopy to unambiguously distinguish
optically triggered electron emission (photoemission) from effects caused purely by the …

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