高功率固体激光驱动器污染控制及片状放大器洁净度改进
Contamination control for high-power solid-state laser driver and improvement of cleanliness in slab amplifiers
摘要
针对高功率固体激光驱动器的安全运行, 提出了覆盖驱动器建设全过程的污染控制方法, 详细介绍了洁净清洗、洁净检测、洁净保护等保障污染控制效果的技术手段, 并介绍了神光-Ⅲ主机装置片状放大器洁净度提升所采取的技术途径, 以及片状放大器光照清洗实验中气溶胶等级随闪光灯照射次数的变化情况。实验结果表明, 神光-Ⅲ主机装置的洁净水平与美国国家点火装置(NIF)接近且优于其他同类装置, 洁净度的大幅提升为装置的安全运行提供了有力保障。
Abstract
The contamination control method covering the whole process of laser driver construction is proposed to ensure the safe operation of high-power solid-state laser driver. The technical means for improving cleanliness level including high pressure washing, cleanliness detection and protection are described, and a technical approach is proposed for improving cleanliness of the slab amplifiers of SG-Ⅲ laser driver. The illuminating cleaning experiment by flashlamp light is introduced. The results indicate that the cleanliness of SG-Ⅲ laser driver is close to NIF, and better than other similar devices.
