Behavior Of A Thin Oil Film Irradiated With 10.6 µm Infrared Beam

A physical model has been proposed to explain the behavior of a thin oil film (~1 μm) on a glass substrate under the influence of IR irradiations; this model is formulated mathematically with a physicochemical hydrodynamics approach. Numerical solutions of the model are shown to fit very well with experimental results. Extrapolation of this model and the experimental method will be discussed as possible application in the study of thin films and very small thickness modulation.
