Production of Optical Quality Free Standing Diamond Wafer; Final rept

摘要

Valdosta Optics Laboratory, Incorporated (VOLI) is pursuing the capabilities of developing synthetic diamond and diamond-like materials, and integrating and implementing these materials in various applications, particularly as a high performance heat spreader for solid state laser (SSL) components, optical coatings, and active engineering materials for micro- electro-mechanical systems (MEMS) and sensors. The current focus is on three key research and development directions, namely: 1) optical quality, highly oriented polycrystalline diamond (PCD) wafers as heat spreader for solid state laser crystals, 2) large area single crystal diamond synthesis, and Further adjustments and additions to the research and development projects/programs will be made as the company's capabilities continue to grow. In order to conduct the planned projects, experimental equipments and instruments, including microwave CVD reactor, DC/RF metal sputtering system, laser cutting system, sample pre- and postdeposition treatment facilities, and material characterization instruments, have been specified, designed, purchased, and installed.
