A detailed discussion is presented of various theories, experiments, and models pertinent to atmospheric effects on the transmission of low-power laser radiation. The effects of molecules, aerosols, and turbulence and their levels in the atmosphere are considered. Specific conclusions and recommendations are given with regard to the state of knowledge in this field, and to models that can be used to predict atmospheric effects that are relevant to comprehensive personnel safety standards.

Unique properties of laser radiation including its monochromatic properties, polarization, high spectral intensity, coherence, narrow beam divergence, the possibility of controlling the pulse duration and radiation spectrum and, finally, the fact that extremely high power and energy create very favorable conditions for the extensive application of lasers to communi cation systems, systems for the lidar sensing and ultra-high-precision ranging, navigation, remote monitoring of the environment, and many other systems operating in the atmosphere. The operative efficiency of the above systems depends significantly on the state of the atmosphere and the corresponding behavior of laser radia tion propagating through it. This circumstance has stimulated the studies of the above regularities during the passt 10-15 years. For the investiga tions to be carried out the scientists were forced to develop new theories and methods for studying the problem experimentally. Moreover, during such investigations some previously unknown phenomena were observed, among them the nonlinear effects accompanying high-power laser radiation propagating through the atmosphere are of paramount importance. Among the nonlinear effects caused by high-power laser radiation inter action with the atmosphere, the effects accompanying the propagation of high-power radiation through the atmospheric aerosols are of particular interest. Aerosols always occur in the atmosphere. It should be noted that the microphysical and optical characteristics of atmospheric aerosols vary widely, this fact causes a great variety in the features of their inter action with radiation.

The detectability of a laser beam through a fog can be predicted fairly accurately for various detector and collecting optical systems if temperature, relative humidity, and fog extinction coefficient are known. Smoke is much more variable and can not be characterized by only its extinction coefficient. Fog and smoke angular scattering patterns determined experimentally are presented.
