Mounting, alignment and integration of large optics in China's high power laser

Research output: Contribution to journalConference articlepeer-review

Abstract

SG-III, a high-power laser facility of China, is constructed to produce 0.18MJ energy for physical experiments under controlled laboratory conditions. Each laser beam requires the ability to align to a millimeter-sized target with a precision of 30 μm (RMS) and the single-beam energy will be up to 3.75 KJ. Arrayed along each beam-path, hundreds of optics must be positioned to stringent tolerances. Therefore, this paper introduces the approaches used by engineers to overcome the technical challenges on precise mounting, alignment and integration of large optics in China's high power laser facility.
