Abstract
A mathematical model of the thermally induced nonlinear propagation of a laser beam in an absorbing fluid medium is developed. The theory includes, identifies, and clearly assesses the relative importance of the different regimes due to conduction, free convection, and/or forced convection cooling. The derived equations of propagation explicitly account for the diffraction effects and permit a straightforward estimate of their relative influence with respect to the thermal distortion.
