摘要
神光Ⅱ大型固体高功率激光装置是我国激光驱动器发展历史的里程碑,其成功研制使我国高功率固体激光工程与技术、聚变物理与基础物理研究实现了全面且本质的跨越式发展。简要概述了神光Ⅱ激光装置研制中创新发展的大量工程方案与技术手段,举例介绍了神光Ⅱ激光装置在近20年来的高质量运行中取得的众多有国际影响力的研究成果。经多方支持和多年持续发展,已经形成数万焦耳级纳秒激光装置、皮秒拍瓦以及飞秒拍瓦激光装置等,这些装置是我国惯性约束核聚变、强场物理、高能量密度物理等研究领域中重要的物理实验核心平台之一。
As a large-scale high-power and sophisticated laser facility,Shenguang-Ⅱ(SG-Ⅱ)is a milestone in the history of laser driver development in China.SG-Ⅱlaser facility has evoked comprehensive and essential leap-style improvements in laser engineering,laser technologies,fusion researches and fundamental physics researches.We provide brief introductions on the great innovative developments of engineering solutions and technologies during the project implementation,and we also list some of the numerous researches of international influence,which have been achieved based on the high-quality operation of SG-Ⅱlaser facility in the past 20 years.With the continuous great progresses of last decade and thanks to the support from leadership departments,facilities with delivery capacity of104 J-level in nanoseconds,103 J-level and petawatt-level in picoseconds,as well as 102 J-level and multi-petawattlevel in femtoseconds have been established,and will surely continue to operate as one of the key platforms on the researches of inertial confined fusion,strong field physics and high energy intensity physics in China.
