As the development of single crystal CVD (Chemical Vapor Deposition) lab created diamond progresses, it is slowly replacing polycrystalline CVD diamond as the material of choice for laser optics. One application of polycrystalline CVD diamond optics, as can be seen in Laser Focus World, is extreme ultraviolet lithography. CVD diamonds’ advantages for this application being:
Polycrystalline CVD diamond is limited in terms of the specifications that it can deliver relative to single crystal CVD diamond due to the existence of grain boundaries between the crystals.
Single crystal CVD diamond allows for “New Levels of Performance” when used in optical applications, this Element Six™ white paper provides some examples:
One of the main challenges of commercializing single crystal CVD lab created diamond applications is the availability and price of the diamond material. Diamond Foundry is currently working on solving that problem and will soon be producing single crystal material at unmatched scale and price.
