We investigated experimentally the evaporation, scorching, and spattering of a layer of liquid (kerosene, petroleum, oil) from a surface of water by a high-power pulsed or cw infrared C02 laser. Convective bulging of the liquid surface is observed, accompanied by circulation near the surface and limitation of the spreading of the film over the surface. Practical applications of the observed effect range from the cleaning of the surfaces of seas, rivers, and lakes to separation and purification of liquids in laboratories.
