Relativistic interaction of short-pulse lasers with underdense plasmas has recently led to the
emergence of a novel generation of femtosecond x-ray sources. Based on radiation from …

The Review covers recent progress in laser-matter interaction at intensities above 10 18 W
cm− 2. At these intensities electrons swing in the laser pulse with relativistic energies. The …

Following the birth of the laser in 1960, the field of" nonlinear optics" rapidly emerged.
Today, laser intensities and pulse durations are readily available, for which the concepts …

We have generated x-ray radiation from the nonlinear Thomson scattering of a 30 fs/1.5 J
laser beam on plasma electrons. A collimated x-ray radiation with a broad continuous …

Enhancement of relativistic third-harmonic generation by using an optically preformed
periodic plasma waveguide was achieved. Resonant dependence of harmonic intensity on …

Enhanced and early relativistic self-focusing of Hermite-cosh-Gaussian (HChG) beam in the
plasmas under density transition has been investigated theoretically using Wentzel-Kramers …

In this paper, the investigation of spatial and temporal dynamics of high power Laguerre-
Gaussian laser pulse propagating inside the plasma medium has been presented. The …

The effect of plasma density ramp on self-focusing of cosh-Gaussian laser beam considering
ponderomotive nonlinearity is analyzed using WKB and paraxial approximation. It is noticed …

The early and strong self-focusing of a Hermite-cosh-Gaussian laser beam in
magnetoplasma in the presence of density ramp has been observed. Focusing and de …

By employing both perturbative and nonperturbative techniques, we study the small and
large amplitude stationary formations of ion acoustic waves in plasma containing …
