FOG DISSIPATION USING A CO2 LASER,

Abstract

Laboratory measurements have been made of the evaporation rate of fog when subjected to an intensity of 5 to 50 W/sq cm of 10.6/microns radiation. The measurements agree with calculations and show that most of the absorbed laser energy goes into heating the air by conduction from the droplet surface. This heated air induces a motion which prevents the laser from completely clearing the fog. A correlation is found which describes the visibility improvement as the fog and power density are varied.
