Abstract

The influence of sample properties on the measured signal has to be investigated, so that measurements of the optical absorption in thin-film coatings by means of the photothermal surface-displacement technique may be precisely performed. Carrying out simultaneously absorption measurements on metal coatings at λ=10.6 μm by using laser calorimetry as well as the surface-displacement technique, the aforementioned influence and the validity of assumptions of the theoretical model, respectively, can be proven. It can be demonstrated that, in contrast to the model, thermophysical coating properties contribute to the probed surface displacement.
