Absorption within the bulk and on the surfaces or dielectric coatings of an optical element under irradiation with a high power or sufficiently tightly focused laser beam causes a spatially and temporally varying temperature distribution in the sample. Using a well-proven photo-thermal setup based upon a highly sensitive Hartmann-Shack wavefront sensor bulk and surface absorption losses can be measured quantitatively.
