In this article, a laser source (He-Ne) laser with maximum output power ( 2.95 mW) was used to study and analyze laser beam when the laser propagates through the atmosphere. Atmosphere layer, also the spot diameter of the ...

Average relative power transmittance is evaluated, by incorporating atmospheric turbulence, for partially coherent cosh-Gaussian, cos-Gaussian, Gaussian and annular beams. For all the collimated versions of these beams, ...
