The absorption by scattering depends on rayleigh scattering and mie scattering.

Laser beam propagation in the atmosphere.

1978 edition by j. Similarity relations and their experimental verification for strong intensity fluctuations of laser radiation m. 8 2 laser propagation in the atmosphere 391 we can then use fig. Absorption in the atmosphere is brought about by molecular constituants.

In papers by fleck morris and feit 2 kandidov and ledenev 3 and konyaev 4 the method of spectral samples was used to generate 2d random phase screens in the problem of propagation of a coherent beam through a randomly inhomogeneous medium and in particular for estimating the efficiency of phase correction of atmospheric distortions. High flux propagation through the atmosphere. All laser systems which involve propagation of the laser beam over a path of several kilometres through the atmosphere usually experience a degradation of their performance due to a variety of natural causes such as the gaseous and particulate constituents fog snow rain and atmospheric turbulence. Laser beam propagation in the atmosphere.

The characteristics of high power partially coherent laser beams propagating upwards in the turbulent atmosphere are studied where the principal features of diffraction nonlinear self focusing and turbulence are considered. Laser beam propagation in the atmosphere topics in applied physics 25 softcover reprint of the original 1st ed. The attenuation of. Mie scattering is related to the dimensions of the particles.

Based on the thin window model the analytical propagation formulae are derived by using the quadratic approximation of the nonlinear phase shift.
