Patent abstract
High-power light absorbers (HPLAs) can exhibit low back-scattered light, mitigate stray light, and withstand high optical power. The absorbers can be used with or without baffling as beam dumps for high-power lasers. An HPLA may include a substrate made of high thermally conductive material with an anti-reflection (AR) coating formed on the substrate. A thin layer of highly absorbing material may be located between the AR coating and substrate. The substrate can be cooled with a fluid, such as water or air.
