Subwavelength antireflection and polarization grating elements: Analysis and fabrication
… These gratings can be used as equivalent anti-reflection coatings and as polarization elements. Since the grating structures are etched into the substrate material, these optical elements are durable and chemically resistant compared to resist gratings. Subwavelength elements may play a …

Broadly tuneable crystalline Raman lasers
… KGW were utilized since the deposition of robust anti-reflection coatings was more feasible on this crystal for such a broad wavelength range (1.1-1.7 µm).;Nevertheless, the first Stokes shift in diamond, being AR-coated for 1.1-1.4 µm operation and pumped by the same VECSEL structure, resulted in …
