Article
The paper is concerned with the effect of multiple scattering and of the limited angular spectrum of scattered emission on the characteristics of nonlinear effects in heterogeneous media. The conditions associated with particularly strong nonlinear scattering effects are analyzed with allowance for the topology of the heterogeneous medium and the c...
Article
Transmission of intense laser beams through heterogeneous scattering media is considered. Effects of intensity limitation, self-recovery of the wave front of a transmitted beam, and bistable reflection associated with the laser-induced self-transparency (suppression of scattering) of such media are predicted because of the compensation of the linea...
Article
Experimental evidence of nonlinear reflection of picosecond light pulses from the interface of two transparent media (glass and liquid) of equal refractive indeces, is obtained. The transient layer at the interface of the two media is found to be very important in this phenomenon. It is shown that nonlinear reflection is caused by variations of the...
Article
The authors present a theoretical analysis of plane wave propagation with nonlinear scattering by static optical inhomogeneities in transparent, absorbing, amplifying media: emulsions, suspensions, a liquid in porous bodies, semiconducting crystals with spatially inhomogeneous impurity distribution, and dispersive systems with close values of the l...
Conference Paper
Wave propagation through a Fabry-Perot interferometer filled with a nonlinear scattering heterogeneous medium is considered. Conditions were found under which the interferometer possesses bistable transmittance and reflectance. Experimental results demonstrating the predicted effects are presented for an interferometer filled with a glass-particles...
Article
Both theoretical and experimental studies of wavefront self-recovery of intense light beam propagating through heterogeneous nonlinear scattering medium are described. The self-recovery of the light beam wavefront is shown to be observed in the definite range of the light intensities when a mismatch of the linear refractive indices of the medium he...
Article
The principal characteristics of the nonlinear scattering of light waves in heterogeneous media are examined with allowance for the blooming effect. It is then shown that, in principle, the effect of nonlinear scattering by static optical inhomogeneities can be used in laser-control devices, such as emission modulators and limiters. It is noted tha...
Article
A theoretical analysis shows that the nonlinear scattering of optical radiation by static optical inhomogeneities should lead to the intensity saturation of the light wave which has passed through the scattering medium. The intensity-saturation effect is confirmed experimentally for dense PbMoO4 crystalline powder. Results indicate that crystalline...
Article
Nonlinear reflection of elliptically polarized light waves from the interface of two isotropic transparent media, is investigated for the first time. Nonlinear Fresnel formulae are obtained. It is shown, that when linear refractive indices are equalized, selfdeformation of the polarization ellipse in nonlinear reflection depends only on incident li...
Article
The brightening effect during nonlinear light scattering by static optical inhomogeneities is investigated theoretically and experimentally using a medium consisting of 100-micron particles of fused quartz dispersed in a mixture of toluene and isobutyl alcohol. It is found that the brightening effect can lead to significant changes in the transvers...
