Laser ablated sub-wavelength structure anti-reflection coating on an alumina lens
Shaul Hanany, Scott Cray, Samuel Dietterich +12
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 designe…
