Techniques for assessing the performance of optical components for infrared high energy laser systems are described. The techniques include photometry and interferometry of large aperture components, diffraction grating efficiency measurements, absorption calorimetry, and reflectometry. A brief summary of the methodology of each type of measurement is presented.
