Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the report is to present a review of the atmospheric effects on laser propagation. Molecular absorption by the earth's atmosphere should not present an insurmountable problem for ruby or neodymium laser systems. However, both the water vapor and the carbon dioxide present in the atmosphere strongly absorb radiation at carbon dioxide wavelengths; this may present a serious problem to systems employing carbon dioxide lasers. Clean air scattering does not seem to be a serious problem. Aerosol scattering, however, is quite severe and will, except in the clearest weather, strictly limit the operation of ground-based laser communication systems. Atmospheric turbulence also poses a serious limitation on the performance of optical communication systems. However, on the basis of the presently available data it does not seem that atmospheric turbulence will necessarily render laser communication systems unfeasible. (Author).
