神光Ⅲ原型装置的全孔径背向散射诊断技术
Full aperture backscatter light diagnostic system on Shenguang-Ⅲ prototype laser facility
摘要
Abstract
In order to have an investigation for the scattering light produced by laser plasma interaction at Shenguang HI laser facility, a new full-aperture backscatter light diagnostic system was developed. According to the properties of Brillouin scattering and Raman scattering, the system gives multiple light splitting and purification, and avoids the effect of stray light. Thus the system has a calibration for the damping factor by using a tailor-made full-aperture laser. The results show that the new full-aperture backscatter light diagnostic system can work stably, and can significantly reduce the effects of stray light. So compared with the original system, the measured data of this system are more reliable.关键词
