Experimental investigation of attenuation and backscatter of laser radiation at λ=2.36 μ and λ=0.63 μ by artificial fogs and smokes
The attenuation and backscattering of laser radiation at X = 2.36μ and A = 0.63μ by artificial fogs and smokes is investigated experimentally. The relationship between the absorption coefficients for these wav...

Reflection of narrow light beams by a dissipating medium
The brightness distribution of multiple back-scattering of radiation is investigated in a plane perpendicular to the beam axis as a function of the density of the artificial mists and smokes. The range of the ...

Rayleigh scattering of nanosecond light pulses
The relation σΔt/σtheory = (τ1/τ)[−exp(−Δt/τ)], obtained by M. Skowronek and J. Alayli for Rayleigh scattering of light pulses, is experimentally investigated. Relative measurements of scattering are made in Ar a...

Forward-scattered optical radiation in a bipolar ionized medium
We study the dependence of the forward-scattered radiation from a point source in wood smoke on the electrical conductivity of the medium. It is shown that as the number of airborne ions in the medium increase...

Propagation of a soliton-like pulse in a weakly nonlinear medium
Numerical methods are used to study the decay dynamics of a soliton-like signal in a medium with a cubic nonlinearity (using the nonlinear Shrödinger equation). We consider the influence of the initial pulse a...
