Abstract

Fluoride HR coatings consisting of middle and low refractive index fluorides often show a higher damage threshold than oxide coatings in the UV range. However, the light scattering level of fluoride HR coatings tend to be higher than oxide ones. In this study, the scattering and surface roughness of fluoride HR coatings for KrF laser were investigated, and also compared with those of oxide HR coatings using Al₂O₃ as high index materials.
