Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

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 …

We demonstrate control of short and long quantum trajectories in high harmonic emission
through the use of an orthogonally polarized two-color field. By controlling the relative phase …

Double ionization of neon with orthogonally polarized two-color (OTC) laser fields is
investigated using coincidence momentum imaging. We show that the two-electron emission …

We have achieved very efficient high-harmonic generation in a two-color laser field using a
long gas jet of He. With the optimization of laser parameters and target conditions, strong …

Based on the strong-field approximation, we report results for high-order harmonic
generation by bi-elliptical orthogonally polarized two-color (BEOTC) fields with frequency …

Orthogonally polarized two-color fields, typically with a frequency ratio of 2: 1, only rarely of
3: 1, have been utilized for a variety of purposes. Driving high-order harmonic generation …

High-order harmonics generation in the laser-induced plasmas produced on the surfaces of
lead-free perovskites is studied. We analyze the harmonics generation in (CH3NH3) 2CuCl4 …

High-order harmonic generation (HHG), attosecond pulse train (APT), isolated attosecond
pulse (IAP), and non-sequential double ionization (NSDI) in the Helium atom under intense …

Enhanced high repetition rate coherent extreme ultraviolet (XUV) harmonics represent
efficient probe of electron dynamics in atoms, molecules and solids. In this work, we used …
