Cr (VI) is a well-known human carcinogen with many water-soluble moieties. Its presence in
both natural and man-made substances poses a risk to public health, especially when …

High harmonic generation (HHG) in atomic gases is generally assumed to originate from
photoelectrons that are not perturbed by neighboring particles. In this paper, we study …

We report, for the first time, that the energy of femtosecond optical laser pulses, E, with
relativistic intensities I> 1021 W/cm2 is efficiently converted to X-ray radiation, which is …

Multiple rescattering processes play an important role in high-order harmonic generation
(HHG) in an intense laser field. However, the underlying multi-rescattering dynamics are still …

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 …

Optical amplifiers in all ranges of the electromagnetic spectrum exhibit an essential
characteristic, namely the input signal during the propagation in the amplifier medium is …

The response of a medium illuminated with a light field can be expanded in many orders in
perturbative non-linear optics. Here we use two multiple-cycle high-intensity laser pulses at …

A wide range of harmonics especially continuum harmonics is a prerequisite for attosecond
pulse generation. One can use longer-wavelength lasers to push the cutoff to a higher order …

In cancer treatment, it is highly desirable to classify single cancer cells in real time. The
standard method is polymerase chain reaction requiring a substantial amount of resources …

A superbright X-ray source with a radiation temperature of~ 1.2 keV making it possible to
create a solid-state plasma whose kinetics is determined by the radiative processes has …
