We theoretically investigate the modulated high-harmonic generation (HHG) driven by an
intense few-cycle infrared (IR) laser field and a weak extreme-ultraviolet (XUV) pulse at a …

An all-optical method for directly reconstructing the spectral phase of an isolated attosecond
pulse (IAP) has been proposed recently [New J. Phys. 25, 083003 (2023)] 1367-2630 …

We investigated experimentally as well as theoretically the ultrafast response of the wave
function of the conduction band (CB) of Si and Zr to a near-infrared laser field using extreme …

We discuss the efficient generation of intense “water window”(0.28–0.54 keV) isolated
attosecond pulses (IAPs) using a mid-infrared (MIR) waveform synthesizer. Our numerical …

We theoretically investigate the coherent control of strong-field high-harmonic generation in
the presence of an isolated attosecond pulse. It is found that the rapid modulation of the …

Parametric amplification of attosecond coherent pulses around 100 eV at the single–atom
level is demonstrated for the first time by using the 3D time–dependent Schrödinger …

We report the realization and characterization of parametric amplification in high harmonic
generation around 100 eV using He gas in a double gas jet arrangement. The delay of the …

We demonstrate strong-field-driven impulsive XUV–x-ray parametric amplification (IXPA)
processes in high-order harmonic generation at the single-atom level by using ab initio …

An all-optical method for directly reconstructing the spectral phase of isolated attosecond
pulse (IAP) has been proposed recently [New J. Phys. 25, 083003 (2023)]. This method is …

The amplification of ultrashort extreme-ultraviolet (XUV) pulses in argon in high-order
harmonic generation processes is studied by using the time-dependent Schrödinger …
