Electron flashlight for nanotechnology

Abstract:
Researchers at the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin, Germany, have developed a novel source of extremely short electron pulses.

The electron source is based on an ultra-sharp metallic needle illuminated with short light pulses from a laser. "With these electron pulses, it is possible to directly observe fast processes in the nanoworld", Claus Ropers explains, who performed the work in collaboration with Daniel Solli, Claus-Peter Schulz, Christoph Lienau and Thomas Elsaesser. The researchers report their findings in the present issue of Physical Review Letters ("Localized Multiphoton Emission of Femtosecond Electron Pulses from Metal Nanotips").
