Abstract
Using a Monte Carlo simulation model, the atmospheric aerosol contributions to laser beam widening for a horizontal propagation path at various elevations were estimated and were compared with beam widening caused by turbulence. In the model, the input parameters were the aerosol number density distribution and index of refraction. The photons were represented by a laser light source. The pathways were calculated on the basis of the scattering characteristics of the atmosphere and a random distribution of scattering events. The results showed that the aerosol contribution to energy loss in the target can be significant, and must be taken into account for laser system design.
