Fog dispersion in conditions of thermal self-defocusing
Abstract
The effect of laser beam self-defocusing on conditions of fog dispersion by means of a 10.6-micron laser which heats the fog, vaporizing the droplets, is examined. Quasi-continuity conditions are formulated for the fog with respect to heat transfer into the interaction zone, and these conditions are used in obtaining integrodifferential equations for electromagnetic field intensity, taking account of self-defocusing. An iterative method is used to obtain approximate expressions for the intensity, and computational results are discussed which show that self-defocusing can significantly effect dispersion speed, and field structure in the channel of dispersion.
