Scio Diamond has demonstrated the first 1 inch single-crystal diamond wafer as a result of its work with the Army Research Lab (“ARL”) to exploit the chemical inertness and high thermal conductivity of the CVD diamond in high power electrical conditioning and thermal management for scalable solid state lasers in directed energy weapons. Scio Diamond has also worked with the Naval Research Lab (Dr. James Butler) on weapons grade diamond laser windows. Further opportunities with ARL are expected to be focused on large area, affordable diamond wafer sizes (1” or larger) for the above-referenced applications.
