Ion-Beam-Sputtered Mid-Infrared Coatings for Hybrid Supermirrors
Lukas W. Perner, Valentin J. Wittwer, Gar-Wing Truong +3
We report on the development of low-loss ion-beam-sputtered (IBS) mid-infrared coatings for hybrid supermirrors. Two highly reflective designs were realized: HR1, a 4-period a-Si/S…

Group Delay Dispersion Measurements of Novel Multilayer Interference Coatings in the Mid-Infrared Spectral Regime
Ulrich Galander, Maximilian Prinz, Lukas W. Perner +1
We present the methods and results for broadband group delay dispersion measurements for all-monocrystalline and amorphous-crystalline hybrid supermirrors, as well as an all-amorph…
