Vortex states of photons, electrons, and other particles are non-plane-wave solutions of the
corresponding wave equation with helicoidal wave fronts. These states possess an intrinsic …

The radiation character of nonlinear Thomson scattering is investigated in the interaction of
Laguerre-Gaussian circularly polarized laser pulses with a single electron in the angular …

The advent of high-power ultra-short laser pulses opens up new frontiers of relativistic non-
linear optics, high energy density physics and laboratory astrophysics. As the laser electric …

In the framework of laser-matter interaction and nonlinear Thomson scattering, we
investigate the three-dimensional (3D) motion trajectories and spatial radiation …

In this paper, nonlinear Thomson scattering in an intense (a0= 6) tightly focused (b0= 3µm)
Gaussian laser pulse is theoretically and numerically investigated to demonstrate varying …

A new scheme for the generation of the terahertz (THz) radiation based on the nonlinear
Thomson scattering is proposed through two moderate-intensity laser fields. It is found that …

The nonlinear Thomson scattering of an electron motion in a combining field constituted by
an elliptically polarized laser and a background magnetic field is investigated. The …

The electron dynamics and the Thomson backscattering spectra for an electron accelerating
in a tightly focused Gaussian laser pulse are first investigated in detail. It is found that for a …

In the present study, we show the calculation of nonlinear Compton scattering with circularly
polarized photons in a cylindrical coordinate using Feynman diagram to calculate photon …

An isolated ultra-short γ-ray pulse is a unique tool for measuring ultrafast-physics processes,
such as imaging intra-nuclear dynamics and inner-shell electron dynamics. Here, we …
