Gaussian beam propagation in maritime atmospheric turbulence: long term beam spread and beam wander analysis

Laser beam propagation in maritime environment is particularly challenging, not only for scattering and absorption due to high humidity, but also for a different behavior of atmospheric turbulence with respect to terrestrial propagation. Recently, a new power spectrum for the fluctuations of the refractive index in the Earth’s atmosphere has been introduced to describe maritime atmospheric turb...

Gaussian Beam Scattering on Two-dimensional Periodic Aperture Array

The diffraction problem of three-dimensional Gaussian beam on the aperture array of rectangular holes is solved. A new algorithm for calculating scattered fields of the beam is proposed. The conditions under which the distortion of the reflected field pattern and the narrowing of the transmitted field pattern appear are studied.

Effects of aperture averaging and beam width on a partially coherent Gaussian beam over free-space optical links with turbulence and pointing errors.

Joint effects of aperture averaging and beam width on the performance of free-space optical communication links, under the impairments of atmospheric loss, turbulence, and pointing errors (PEs), are investigated from an information theory perspective. The propagation of a spatially partially coherent Gaussian-beam wave through a random turbulent medium is characterized, taking into account the ...
