| Abstract | ||
| In this work, the atmospheric attenuation of laser beam due to the the scattering by the atmospheric particle such as fog, mist, and haze or dust has been calculated as a function of visibility (visual range).the theoretical results show that the laser wavelength in the near infrared region 1.8µm have attenuation more than middle infrared regions 3.11 µm and far infrared region 8.5µm although these wavelength have transmittance windows also these result show that, in fog condition where visibility less than 0.5km the atmospheric attenuation of laser beam is independence of laser wavelength . These results are obtained for horizontal path and confirmed by comparison with published data. | ||
