Waveform sampling on an atomic scale
概要
The manipulation of matter on an atomic scale and ultrafast timescale occurs in important processes such as electron transfer, molecular motion and chemical reactions. Visualization of these spatiotemporal dynamics is a long-standing goal for the scientific community. In recent years, field-driven nanoscopy, an emerging field of nanophotonics, has opened new avenues for studying the non-perturbative regime of light–matter interactions with extremely high spatiotemporal resolution. Since such light–matter interactions are sensitive to not only the amplitude of the electric field but also its phase, the precise control of carrier-envelope phase (CEP) of ultrashort laser pulses is crucial.
