The world’s fastest electron microscope captures electron motion at a temporal resolution of one attosecond, enabling scientists to observe electron behavior with unprecedented precision.

Developed by researchers at the University of Arizona, who have published their work in the journal Science, the microscope uses electron pulses at the speed of a single attosecond — or one quin ...

Attosecond physics is the study of atomic-scale electron dynamics in matter. Such dynamics are probed using attosecond light pulses: attosecond pulses present the same timescale of light-matter ...

A new gating scheme based on polarization control and second-harmonic generation is greatly simplifying the production of isolated attosecond pulses. Attosecond pulses — flashes of light lasting ...
