As applied to laser acceleration of ions, we have constructed an analytical solution to the Cauchy problem for the kinetic equation, which describes the radial motion of particles under the action of a ponderomotive force in a tubular focus of a high

The Maxwell equations-based 3D-analytical solution for the terahertz (THz) half-cycle electromagnetic wave transition radiation pulse has been found. This solution describes generation and propagation of transition radiation into free space from lase

Nonlinear Laser Radiation Absorption Due to Relativistic Plasma Resonance in an Inhomogeneous Plasma
Publikováno v:
Journal of Experimental and Theoretical Physics. 133:236-252
We have developed an analytic theory of the nonlinear resonant absorption of electromagnetic radiation in an inhomogeneous plasma with account for the relativistic nonlinearity of the plasma field being excited near the critical density of the plasma

We use the qualitative, simplified modeling, and approximately self-consistent nonlinear-optical approaches to explain the nature of the regime under which relativistically intense laser pulses propagate in a plasma to distances exceeding the Rayleig

We present a theory on harmonic generation by relativistic plasma resonance mechanism in an inhomogeneous laser plasma. We find a transverse component of the resonance–enhanced electric field and electron velocities near the plasma critical density

In contrast to the existing theories of the relativistic self-focusing of a light beam in a plasma, the problem of a steady self-focusing light beam with a given input Gaussian radial intensity distribution has been analytically solved approximately

Using the renormalization-group approach, we consider an analytic theory describing the formation of a self-focusing structure of a laser beam in a plasma with relativistic nonlinearity for a given radial intensity distribution at the entrance and de
