Paper Abstract

The surface of a heavy hydrocarbon liquid film is deformed due to inhomogeneous heating with a Gaussian laser beam. The surface profile and the liquid velocity distribution are calculated as functions of time. The liquid surface behaves as an aspherical mirror whose focal properties are controlled by varying the laser beam intensity. This phenomenon allows obtention of self and cross correlations of low-power laser beams. Optical properties and applications of this laser-controlled adaptive mirror are discussed.
