Effect of Laser Conditioning on Surface Modification and Laser Damage Resistance of SiO₂ Antireflection Film

Crystals, 2023
SiO2 sol-gel antireflection film coated on fused silica can reduce the reflection loss and improve the transmittance of the optical component, although it is still prone to laser induced damage. Laser conditioning is an effective way to improve the laser

Ultra-antireflective synthetic brochosomes [PDF]

Nature Communications, 2017
AbstractSince the early discovery of the antireflection properties of insect compound eyes, new examples of natural antireflective coatings have been rare. Here, we report the fabrication and optical characterization of a biologically inspired antireflective surface that emulates the intricate surface architectures of leafhopper-produced brochosomes ...
