  • Anisotropy effect on multi-Gaussian beam propagation in turbulent ocean 
    Ata, Yalçın; Baykal, Yahya (Chinese Laser Press, 2018-08-10)
    Average transmittance of multi-Gaussian (flat-topped and annular) optical beams in an anisotropic turbulent ocean is examined analytically based on the extended Huygens-Fresnel principle. Transmittance variations depending ...
  • Intensity fluctuations of laser array beams in non-kolmogorov turbulence 
    Gerçekçioğlu, Hamza; Baykal, Yahya (IEEE-Inst Electrical Electronics Engineers Inc, 2015-09)
    On-axis intensity fluctuations of laser array beams are evaluated when they are used in a weakly turbulent non-Kolmogorov atmosphere. Our formulation of the scintillation index is based on the Rytov method, which in the ...
  • Intensity fluctuations of multimode laser beams in underwater medium 
    Baykal, Yahya (Optical Soc Amer, 2015-04)
    In an oceanic optical communications link, the received intensity fluctuations, quantified by the scintillation index, are formulated and evaluated when a multimode laser is used. The variations of the scintillation index ...
  • Optical Propagation in Unguided Media 
    Baykal, Yahya (Springer - Verlag, 2016)
    This chapter provides fundamentals of light propagation in unguided media and particularly discusses turbulence of transmission environment. The degradation effects of turbulence in the received signal of an OWC system are ...
  • Scintillation of Laser Beams in Weak Atmospheric Turbulence for Aerial Vehicle in the Use of LIDAR 
    Gercekcioglu, Hamza; Baykal, Yahya Kemal (2022)
    Formulation of on-axis scintillation of laser beams is found in weak atmospheric turbulence for aerial vehicle in the use of light detection and ranging (LIDAR) systems by employing the Rytov method. The formulation derived ...
