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 …

We propose a method to implement absorbing layers for the numerical solution of the time-

The wave function of an electron interacting with a finite-range potential and an intense low-
frequency laser pulse is analyzed within the adiabatic approximation. The closed analytic …

Abstract Characterization of an isolated attosecond pulse (IAP) in the extreme ultraviolet
(XUV) or soft x-ray (SXR) region is essential for its applications. Here we propose to retrieve …

Interpretation of strong-field phenomena is mostly based on the analysis of classical electron
trajectories in an intense laser field, whose specific properties determine general features of …

We address extreme-ultraviolet (XUV) initiated high-order harmonic generation (XIHHG) in
argon atoms observing a resonant enhancement of the high-energy harmonics when the …

The nonlinear response of an atomic system interacting with short extreme ultraviolet (XUV)
and infrared (IR) pulses is considered within the adiabatic approach (for an IR field) and the …

High-order harmonic generation by two linearly polarized fields that enclose an arbitrary
crossing angle θ is investigated using the strong-field approximation. We investigate the …

High harmonic generation of Hydrogen is investigated under the action of two-color and
three-color laser field. Effect of relative strengths of different components of the laser field as …

An all-optical method is suggested for the metrology of an isolated, pulse-to-pulse stabilized
attosecond pulse. It is shown analytically that high-order harmonic generation (HHG) yield …
