Abstract

A theoretical analysis is made of the wavefront reconstruction and reversal of nonmonochromatic radiation in stimulated scattering. It is shown that several wavefront reconstruction or reversal conditions are possible for nonmonochromatic excitation. Expressions are obtained for the scattered field amplitudes. The effect of the type of time dependence of the exciting radiation on the character of the wavefront reconstruction or reversal effect is analyzed.

Influence of saturation on the quality of wavefront reversal in the case of stimulated scattering of spatially inhomogeneous pump radiation

I Yu Anikeev, Iosif G. Zubarev, С И Михайлов

A theoretical investigation is made of stimulated scattering of spatially inhomogeneous radiation under saturation conditions. A system of kinetic equations describing the interaction between the pump radiation and Stokes waves, correlated and uncorrelated with the exciting field, is derived and solved. A quantitative criterion is derived for the quality of wavefront reversal in the case of generation of Stokes radiation from the spontaneous noise and also in the case of a "Brillouin" amplifier.

Theory of wavefront reversal of radiation having a spatially inhomogeneous average intensity distribution

Igor' M Bel'dyugin, Iosif G. Zubarev

A spectral method is used in an attempt to find a unified approach to describe several variants of wavefront reversal in stimulated scattering: in a waveguide and when spatially inhomogeneous and single-mode radiation is focused by a lens. It is found that this involves allowing for a specific correlation between the spatial spectral components in the expansion of the pump field. Approximate solutions are found for the scattered field in these cases.

Wavefront reversal in stimulated scattering of two-frequency pump radiation

Кочемасов Геннадий Григорьевич, Valeri D. Nikolaev

The quasioptic approximation is used to study the influence of pump radiation nonmonochromaticity on the spatial and angular characteristics of the scattered radiation. It is shown that the temporal noncoherence may greatly distort the angular spectrum of the Stokes component of the scattered radiation, compared with the case of monochromatic pumping.

Wavefront reversal in stimulated light scattering in a focused spatially inhomogeneous pump beam

N. B. Baranova, Boris Ya Zel'dovich, Vladimir V. Shkunov

A theoretical analysis is made of stimulated light scattering in a pump beam possessing both fine-structure inhomogeneity (and thus, "gray" divergence) and a continuously varying amplitude and phase envelope due to focusing of the beam with a lens into an unbounded medium. An equation is derived to describe the gain of the pump-reproducing field component, and a solution of this equation, excitable by spontaneous radiation noise, is found in the constant pump field approximation. In this case, the scattered wave is localized in a narrow (compared with the pump wave) near-axial zone and, unlike scattering in a waveguide, the reproduction of the pump wave is partial and dependent on the correlation between the "gray" and diffraction-limited divergence. The disagreement between this theoretical conclusion and the complete reproduction observed earlier experimentally indicates the importance of saturation effects in the scattering of focused beams.

Theory of amplification of the first Stokes component in a nonmonochromatic pump field under stimulated Raman scattering conditions

Igor' M Bel'dyugin, E M Zemskov, V I Chernen'kiĭ

A theoretical analysis is made of the problem of parallel amplification of the Stokes signal in a nonmonochromatic spatially inhomogeneous pump field in stimulated Raman scattering. Expressions are obtained for the spatial and temporal characteristics of the process of amplification of the Stokes signal. It is shown that in the course of amplification the slowly varying amplitude of the Stokes signal field becomes similar to the slowly varying amplitude of the pump field. The relationships obtained apply also, subject to certain restrictions, to other types of scattering.

Theory of stimulated scattering of nonmonochromatic radiation

Igor' M Bel'dyugin, Michail G. Galushkin, O. I. Rechkin

A theory is developed of stimulated scattering of nonmonochromatic radiation whose spectral width is much greater than the spontaneous scattering line width or the frequency shift of the Stokes wave. It is shown that scattering of nonmonochromatic incident radiation under coherent conditions may take place as efficiently as for monochromatic pump radiation. The results apply to various types of stimulated scattering, in particular, to stimulated thermal scattering and stimulated scattering in media which are in thermodynamic nonequilibrium.
