Abstract

Two kinds of polarizer coatings were prepared by electron beam evaporation, using HfO₂–SiO₂ mixture and HfO₂ as the high-refractive-index materials, respectively. The HfO₂–SiO₂ mixture layer was implemented by coevaporating SiO₂ and metal Hf, the materials were deposited at an oxygen atmosphere to achieve stoichiometric coatings. The certain HfO₂ and SiO2 content ratio is controlled by adjusting the deposition rate of HfO₂ and SiO₂ using individual quartz crystal monitor. The spectral performance, surface and interfacial properties, as well as the laser-induced damage performance were studied and compared. Comparing with polarizer coating using HfO₂ as high-refractive-index material, the polarizer coating using HfO₂–SiO₂ mixture as high-refractive-index material shows better performance with broader polarizing bandwidth, lower surface roughness, better interfacial property while maintaining high laser-induced damage threshold.
