Chemically generated CO{sub 2} laser pulses at 10.6 {mu}m have been used to clear a 5 cm diameter hole through a stratus-like cloud in a laboratory cloud chamber. The results show that 100% clearing can be achieved. The mechanism is shown to be droplet shattering followed by evaporation. Under the conditions of the experiment, the channel closure is dominated by turbulent mixing and not droplet recondensation. 14 refs., 9 figs.
