LLNL Uses Simulation to Investigate Laser Repair Techniques

Manyalibo Matthews, Lawrence Livermore National Laboratory (LLNL), CA, USA

位于加利福尼亚的劳伦斯利弗莫尔国家实验室(Lawrence Livermore National Laboratory,简称 LLNL)负责管理国家点火装置(National Ignition Facility,简称NIF),这里拥有世界上最大、功率最高的激光器。但是,反复使用这个激光器会对系统中用于引导和聚焦激光的光学元件产生损害。

Manyalibo Matthews 是 LLNL 材料科学部的副组长,他与团队成员正在研究激光系统中熔融石英光学元件的修理和保养技术。下载并阅读文档,了解他们如何使用 COMSOL Multiphysics® 软件来模拟激光与材料间的相互作用。研究人员借助仿真对红外线(IR)脉冲激光微成形/微机械、慢速退火,以及激光化学气相沉积(L-CVD)进行了探索。同时还优化了一项称作选择性激光烧结(SLM)的 3D 打印增益工艺。
