Laser ablated sub-wavelength structure anti-reflection coating on an alumina lens

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Shaul Hanany, Scott Cray, Samuel Dietterich, Jan Dusing, Calvin Firth | Summary: We used laser ablation to fabricate sub-wavelength structure anti-reflection coating (SWS-ARC) on a 5 cm diameter alumina lens. With an aspect ratio of 2.5, the SWS-ARC are designed to give a broad-band low reflectance response […]
