Single Electron Imaged with Quantum Strobe

Reader and frequent commenter Rocket Roo posted this comment on a relatively old post. I believe it is worth starting a new thread on it.

A quantum stroboscope based on a sequence of identical attosecond (10-18 s) pulses has been used to release electrons into a strong infrared laser field exactly once per laser cycle (coherent scattering). The resulting electron momentum distributions are recorded as a function of time delay between the IR laser and the attosecond pulse train using a velocity map imaging spectrometer. More details can be read at See the movie at
