Paper Abstract

With a modified standard coating plant simultaneous evaporation was applied to produce IR-coatings with improved performance for different applications. In one case, a single layer coating, quasi-homogeneously mixed from two different materials, achieves lower reflectance and higher laser damage thresholds at 2.78 micrometers. In another case, for a multilayer coating, 'soft' transitions between the individual layers yield a layer stack with a completely different structure with different properties, e.g. showing significantly reduced scatter.
