Title: Formation of a reflected wave under propagation of a pulse with high peak intensity through a Kerr medium

Abstract

Propagation through a Kerr medium of short pulses depending only on the longitudinal coordinate is investigated. High values of the peak intensity are considered for which the nonlinear part of the relative permittivity is on the order of unity. When a short pulse propagates through such a medium, the leading edge of the pulse is extended, while the trailing edge runs into the slowly propagating central part of the pulse; shock waves are generated at the trailing edge, giving rise to high spatial frequencies and backward reflected radiation. The duration of the pulse increases due to the high-frequency jet that forms at the trailing edge, and the peak intensity decreases. The spectrum of the backward reflected radiation is investigated as a function of the peak intensity of the pulse and the characteristics of the time dispersion of the medium.

  • The polarisation response of quantum systems modelling silver and xenon atoms in the field of a high-intensity femtosecond Ti : sapphire laser (photon energy h{omega} Almost-Equal-To 1.5 eV), has been investigated by direct numerical integration of the Schroedinger equation. The applicability ranges of the perturbation theory and polarisation expansion in powers of field are determined. The contributions of excited atoms and electrons in the continuous-spectrum states to the polarisation response at the fundamental frequency, which arise as a result of excitation and photoionisation, are analysed. It is shown that specifically ionisation changes the sign of dielectric susceptibility with an increasemore » in radiation intensity for the systems under consideration.

  • A multimode plane wave pulse propagates through a rapidly varying, statistically stationary, layered medium with high contrast between the material parameters in consecutive layers. The wavelength of the pulse is long in comparison to a typical layer thickness. The pulse shape changes on a depth scale that is large in comparison to the wavelength. The pulse broadens and attenuates due to multiple scattering by the layered structure. The authors find simple asymptotic formulas for the travel time and the pulse shape that account for fine layering effects. The limiting pulse shape is given by a convolution of the incident pulsemore » shape with a Gaussian whose squared width is deterministic; i.e., it is independent of the particular realization of the random medium, and it depends on the second-order statistics of the random medium only. The new theory consolidates the localization phenomenon for waves with effective medium theory. Wave propagation in layered media is a phenomenon of great interest in seismics, ocean acoustics, electromagnetic remote sensing, borehole acoustics, and so on.« less
  • The study of the propagation of an electromagnetic ultrashort pulse in a Kerr medium with impurity atoms under quasi-resonance conditions is reported, which demonstrates the efficiency of the unitary transformation method in nonlinear optics. An equation is derived, which differs from the known equations describing the evolution of a pulse envelope and takes into account the dispersion of the nonlinear response and the dispersion of group velocities. (nonlinear optical phenomena)
  • The average intensity and the degree of coherence of a beam reflected from a wave front inverting mirror in a randomly inhomogeneous medium are studied. The conditions for the WFI mirror to compensate for the effect of turbulence in the energy flux distribution and the coherence properties of the reflected radiation are discussed. It is shown that, for a sufficiently large ratio of the WFI mirror diameter to the source diameter, the degree of coherence at the center of the reflected beam can be made close to unity, regardless of whether the conditions to compensate for the effect of turbulencemore » are satisfied for the majority of the energy flux of the reflected radiation.« less
