Abstract

Two kinds of hafnia-silica polarizer coatings were prepared by electron beam evaporation, using hafnia-silica mixture (MPOL) and hafnia (POL) as the high refractive index materials, respectively. The spectral performance, surface and interfacial properties, as well as the laser induced damage performance were studied and compared. The M-POL coating shows better performance with broader polarizing bandwidth, lower surface roughness, better interfacial property, while maintaining high laser induced damage threshold.
