  We experimentally demonstrate that the transmission of a 1030~nm, 1.3~ps
laser beam of 100 mJ energy through fog increases when its repetition rate
increases to the kHz range. Due to the efficient energy deposition by the laser
filaments in the air, a shockwave ejects the fog droplets from a substantial
volume of the beam, at a moderate energy cost. This process opens prospects for
applications requiring the transmission of laser beams through fogs and clouds.
