Abstract

In this paper we report our recent measurements of thermal conductivities of optical coatings by two photothermal methods, namely photothermal reflectance and photothermal deformation technique. We will first give a brief introduction of the principles and the apparatus for the experiments, and then present the measured thermal conductivities of various coatings including oxide layers (SiO₂, ZrO₂, Ta₂O₅) on BK₇ glass, a MgF₂ film on MgF₂ substrate and metallic films (Au). The results are compared between the two methods as well as with those previously reported by other techniques and those of the related bulk materials.
