TL;DR: A robust generation method of intense isolated attosecond pulses is proposed and demonstrated, which enable us to perform a nonlinear attose Cond optics experiment and is the shortest and highest-energy pulse ever with the ability to induce nonlinear phenomena.

TL;DR: The proposed method enables the requirements for the pump pulse duration to be relaxed but also to reduce ionization of the harmonic medium, which opens the door to create an intense isolated attosecond pulse using a conventional femtosecond laser system.

TL;DR: In this paper, a method to coherently control electron dynamics is proposed using a few-cycle laser pulse in combination with a controlling field, which not only broadens the attosecond pulse bandwidth, but also reduces the chirp; thus an isolated $80\text{\penalty1000-\hskip 0pt} as}$ pulse is straightforwardly obtained, and even shorter pulses are achievable by increasing the intensity of the controlling field.

TL;DR: The isotopic effects in the energy shift of the HHG spectra caused by the nuclear motion of the molecules are measured to pave an accessible route toward monitoring the ultrafast nuclear dynamics and even tracing a chemical reaction in real time.

TL;DR: Attosecond-scale probing of the laser-induced dynamics in molecules using the method of high-harmonic spectroscopy, where laser-driven recolliding electrons on various trajectories record the motion of their parent ion.
