Attenuation of laser beam propagation in the atmosphere

Abstract

In this search I am calculated theoretical model for attenuation of laser
beam due to the scattering by the atmospheric particle (fog, mist, haze and dust)
as a function of visual range (visibility). the theoretical results show that the
laser wavelength in the Ultraviolet region 0.337 µm have attenuation more than
Visible regions, 0.6328µm and near infrared region 1.06µm, also these result
show that, in fog condition where visibility is less than 0.6km, the atmospheric
attenuation of laser beam is independence of laser wavelength.
