Abstract:

It has been suggested that haze and fog may be dissipated by using a 10.6 micron laser beam. This radiation is strongly absorbed by liquid water but only weakly absorbed by water vapor. Thus, the laser selectively deposits its energy in the water droplet, ultimately evaporating it. In this paper, the physics of fog removal by a CO2 laser is explored and the possibility of clearing airport runways is evaluated. While initial estimates of the power required to clear a runway are large for present-day laser devices, they may not be excessive requirements for future systems. Author
