Progress on ultra precision manufacturing technology of large-aperture high-power laser optics

The construction of high-power solid-state laser facility for inertial confinement fusion requires to precisely control the full-spatial frequency error, and realize efficient mass-manufacturing of large-aperture optics. This review summarizes the recent critical progress in manufacturing of large-aperture optics in high-power laser facility. It also emphasizes the technologies such as single point diamond fly-cutting, and aspheric ultra-precision grinding, as well as deterministic polishing, based on the deterministic ultra-precision process manufacturing method. In addition, the application status of these key technologies in the mass-manufacturing chain was stated specifically.
