Abstract
A laser ablated product exhibits a diffraction severity of less than about 5. The product may include a substrate that is at least partially transparent to visible light, and a periodic structure formed on at least one surface of the substrate by laser ablation. The periodic structure has a period in at least one direction of at least about 4,500 nm to at most about 850,000 nm, and the periodic structure has a peak-to-valley dimension of less than about 25 nm. The product may be employed in an electrochromic device, such as a vehicle rearview mirror assembly.
