Investigation of Coherent and Incoherent Laser Beams Propagation Through Turbulent Atmosphere
In this paper propagation of combined laser beam through atmosphere is investigated. Laser beam is combined via lens array arrangement. Turbulence is considered as an affecting factor of atmosphere and its effects on transverse coherence length (Fried parameter), peak intensity, propagation efficiency, and spot size of the laser beam is investigated. Coherent and incoherent combined beam are co...
متن کاملPicosecond Laser Pulse Distortion by Propagation through a Turbulent Atmosphere
We have been investigating the influence of atmospheric turbulence on the propagation of a picosecond laser pulse. The figure of merit of presented results is the time of propagation, its absolute delay and jitter. Phase wavefront deformation or beam profile changes were not studied. The correlation of the atmospheric turbulence with the propagation delay fluctuation was measured. The research ...

متن کاملOptical detection of laser or scattered radiation transmitted through the turbulent atmosphere.
Photoelectron counting distributions are obtained for radiation, consisting of a coherent and a chaotic component, after passage through the turbulent atmosphere. Independent additive background radiation is also taken into account. The counting distributions broaden markedly, and their peak occurs at decreasing count numbers for increasing turbulence. Plots of the distributions are presented f...
