Abstract

A novel method for figuring and polishing diamond surfaces is described. It is a three step process, consisting of (1) a diffusion smoothing step using carbon reaction with certain materials at elevated temperatures (such as hot iron, molten rare earth metals, etc.), (2) a laser polishing and figuring step where UV laser ablation actively coupled with in situ interferometry provides the desired diamond figure and (3) an ion beam assisted superpolishing step, where ion beam technology is used to provide the final surface finish.
