Guidelines for Estimation and Characterization of the Thermo-Mechanical Properties of New Optical Materials

摘要

Methods are discussed for the estimation and determination of the thermomechanical properties of new optical materials for laser and nonlinear applications. The goal is to characterize the important properties before materials synthesis, where possible, or for properties where no reliable estimation method is available, a secondary goal is to perform accurate measurements on small samples. The thermomechanical properties of primary emphasis for these applications are fracture toughness, an intrinsic measure of the strength of brittle materials, thermal conductivity, thermal expansion and the elastic constants.
