Scattering losses of oxide and fluoride coatings for lasers

Total integrated scattering measurements (- 632.8 nm) and scattering spectroscopy from the VIS to the UV region are used to investigate oxide and fluoride single layers as well as multilayer coatings for laser applications. When examining single films, information on fundamental scattering phenomena can easily be derived. Appropriate substrate-film designs enable volume scattering of the single layer to be separated from interface scattering. So conclusions can be drawn with respect to both roughness correlation properties and film morphology.
