The generation of sub‐optical‐cycle, carrier–envelope phase‐stable light pulses is one of
the frontiers of ultrafast optics. The two key ingredients for sub‐cycle pulse generation are …

In this review, we will focus on the theoretical aspects in observing and controlling the
electronic dynamics in few-electron atoms and molecules by attosecond pulses in different …

Manipulation of electron dynamics calls for electromagnetic forces that can be confined to
and controlled over sub-femtosecond time intervals. Tailored transients of light fields can …

The patterning of graphene is useful in fabricating electronic devices, but existing methods
do not allow control of the number of layers of graphene that are removed. We show that …

Achieving the control of light fields in a manner similar in sophistication to the control of
electromagnetic fields in the microwave and radiofrequency regimes has been a major …

Ultimate control over light entails the capability of crafting its field waveform. Here, we detail
the technological advances that have recently permitted the synthesis of light transients …

Ultrafast science has begun to tackle the measurement of electronic and chemical
processes taking place on the few-femtosecond-to-attosecond timescale. This field requires …

Time-resolved investigations of ultrafast electronic and molecular dynamics were not
possible until recently. The typical time scale of these processes is in the picosecond to …

We report on two novel routes to generating a train of attosecond pulses from a broad
discrete spectrum in the near-infrared–visible–ultraviolet range. One extends an integer …

High harmonics emitted from aligned molecules driven by intense femtosecond laser pulses
provide the opportunity to explore the structural information of molecules. The field-free …
