Numerical study of phase conjugation in stimulated backscatter with pump depletion
TLDR
In this paper, phase conjugation in stimulated backscatter of a focused aberrated beam, including the effects of pump depletion, has been investigated and shown to have a prominent axial spike closely matching that of the incident beam; however, the near field distribution had large and rapid spatial inhomogeneities.About:

A review of stimulated Brillouin scattering excited with a broad-band pump laser
TL;DR: In this article, the authors studied the effect of pump phase fluctuations on SBS amplitudes and showed that the effect depends on the coherence length of the pump and the amplitude of the SBS medium.

Beam combination through stimulated Brillouin scattering
TL;DR: Stimulated Brillouin scattering (SBS) is used for multiple-beam combining by overlapping the beams in the SBS interaction volume and for phase control by backseeding the interaction volume as discussed by the authors.
Journal ArticleDOI
Stimulated Brillouin scattering phase-conjugation fidelity fluctuations
TL;DR: Shot-to-shot fluctuations in the far-field fidelity of stimulated Brillouin scattering phase-conjugate mirrors in the saturated reflectivity regime under various experimental conditions reflect a partial breakdown in the discrimination mechanism that selectively amplifies the conjugate mode above the stimulated BrillOUin scattering noise seed.

Saturation and Spectral Characteristics of the Stokes Emission in the Stimulated Brillouin Process
TL;DR: In this paper, the saturation effect in the stimulated Brillouin scattering of coherent light waves was analyzed and two coupled first-order nonlinear equations for the intensities of the primary and Stokes waves were proposed.

Correction of phase aberrations via stimulated Brillouin scattering
Victor Wang,Concetto R. Giuliano +1 more
TL;DR: Quantitative measurements on the correction of severely aberrated laser beams using stimulated Brillouin scattering (SBS) at 0.69 microm are obtained and it is shown that under certain conditions SBS can be used to restore an aberrated optical beam to its original unaberrated condition.

Theory of phase conjugation by stimulated scattering in a waveguide
TL;DR: In this article, the backward optical wave stimulated by a multimode, monochromatic, incident optical wave in a waveguide filled with a transparent nonlinear medium was considered, and conditions on guide length, area, mode number, and Stokes shift were derived in order that a given high percentage of the power in the backscattered field be the phase conjugate of the incident field.

Influence of certain radiation parameters on wavefront reversal of a pump wave in a Brillouin mirror
TL;DR: In this paper, a study was made of wavefront reversal, accompanying stimulated Brillouin scattering in various media, and of the way it was affected by the geometrical, temporal, and polarization characteristics of the exciting radiation.
