Abstract
We propose to survey the state-of-the-art of VIS high reflectors. Specifically, mirrors must meet a minimum reflection of 99.5% at normal incidence for 532 nm. The participants select the coating materials, design, and deposition method. The samples will be damage tested using the raster scanning protocol with a 5-ns pulse length laser system operating at 100 Hz at a single testing facility to enable direct comparison among the participants. Details of the deposition processes, cleaning method, coating materials, and layer count will be shared.
