Ultra-Precision Manufacturing Technology of High Power Laser Optics
A high power solid laser facility used for inertial confinement fusion (ICF) demands over ten thousands of large aperture optics. Extremely precise machining accuracy specified over a continuous range of spatial frequencies (μm-1 level to m-1 level) as well as high resistance to laser damage is the fundamental requirement for high power laser optics. Advanced and deterministic optical manufacturing technologies are the basis to realize mass manufacturing of the large aperture laser optics. In this review, recent progresses in the ultra-precision manufacturing technologies and equipment for high power laser optics are summarized. Advances of ultra-precision grinding, rapid conformal polishing, deterministic polishing, ultra-precision fly-cutting, and low-density defect manufacturing technologies are emphasized. Besides, future developments of fabrication of high power laser optics are analyzed.
