Velocity of a fog-clearing front in the case of gasdynamic explosions of aerosols in laser beams

An analysis is made of effective fog clearing under conditions of gasdynamic explosions of aerosols. It is shown that explosion-generated shock waves prevent establishment of a steady-state clearing wave, so that the most effective clearing is achieved employing pulses of duration less than 10^-7 sec (corresponding to the time of appearance of significant scattering by shock waves). A calculation is made of the velocity and depth of fog clearing by a single pulse.
