  • Experiments using ultrafast mid-infrared light pulses on nanostructures access a new regime in photoelectron emission, revealing classical sub-cycle electron dynamics in optical near-fields and breaking a diffraction limit in strong-field physics.

  • Nanoscale metallic tips are a useful source of electrons for material characterization. It is now shown how terahertz radiation can provide precision control and enhancement of photoelectron emission from these sources. The approach can shape the spectrum of the electron pulse, which could pave the way to improvements in ultrafast electron diffraction and transmission electron microscopy.

  • By driving ultrafast soliton molecules with an all-optical external perturbation and monitoring their response in real time, a form of spectroscopy of soliton molecules akin to optical spectroscopy of chemical bonds is introduced.

  • Researchers report the spontaneous appearance of discrete frequency modes in a real-time experimental investigation of pulsed modulation instability in an optical system. These findings are expected to impact modulation instability-induced characteristics across a broad range of physical situations and technological systems, including free-electron lasers.
