Abstract
Chemical vapour deposited bulk diamond products have already found significant applications in high power laser systems including heatspreaders, output couplers and active components such as raman shifting or beam combining crystals. However, as new applications require ever increasing power densities the synthesis, processing and integration of diamond parts to fully utilise its exceptional properties becomes more challenging. We report on innovation in synthesis and processing of diamond that enables its properties to be fully exploited. Diamond parts with larger dimensions than previously achieved at extremely low defect density have been synthesised, and processed to flatness and roughness significantly beyond those previously reported. The achievements reported have allowed a number of exciting new developments in the use of diamond in high power laser systems.
