The clearing of polydisperse water droplet aerosol upon exposure to a laser beam at high altitudes in the atmosphere with the wind at low pressures and temperatures is considered. It is shown that the linear dependence between the evaporation rate and the radiation intensity is violated for diffusive–convective and subsonic regimes of evaporation. The aerosol clearing problem is solved with the use of the water droplet size distribution. This solution is compared with the liquid water content approximation. Applicability limits of the liquid water content approximation are extended to include the diffusive regime of evaporation.
