Thermal Transport Properties of Optical Thin Films

Abstract

This paper presents results of a successful four year effort funded by the Air Force to develop a measurement system for the study of optical-thin-film thermal transport properties. Data are presented on several coated samples. Characteristic features of the data are interpreted in terms of behavior expected on the basis of solutions of the heat diffusion equation. Comparisons are made between observed coating data and model predictions based on handbook data on coating materials in bulk format. These comparisons show close agreement for measurable properties in the special cases studied. The data are found to be free of unexpected structure.
