Laser beam fluctuations for long distance propagation in the turbulent atmosphere
V. L. Andriichuk, O. O. Chumak, L. A. Derzhypolska +1
The method of photon distribution function (PDF) is used to study fluctuations of light beams propagating through a turbulent atmosphere. Our analysis concerns the regime of satura…

Fourth-order moment of the light field in atmosphere
Roman Baskov, Oleksandr O. Chumak
The quasiclassical distribution function for photon density in the phase space is obtained from solution of the kinetic equation. This equation describes propagation of paraxial la…

Laser-beam scintillations for weak and moderate turbulence
Roman A. Baskov, Oleksandr O. Chumak
The scintillation index is obtained for the practically important range of weak and moderate atmospheric turbulence. To study this challenging range, the Boltzman-Langevin kinetic…
