| 中文简介 |
激光制造与材料加工已经在许多工业部门广泛应用，包括能源、汽车、电子、生物工程、医疗、航空航天等。激光与物质的相互作用是一个复杂的多物理过程，涉及激光吸收、电子激发、热/物质输运、流体/固体力学和相态/微结构变化。深入理解这些基本物理机理对提升激光制造与加工过程的精度、效率与产品质量至关重要。课程将让学生对激光、光学、激光与物质相互作用机理、各种先进的激光制造与材料加工技术有基础的认识与理解。课程还将介绍微/纳米制造、3D打印、材料的3D结构测定、器官组织加工、冲击强化等技术。 |
| 英文简介 |
Laser-based manufacturing and material processing have been widely used in many industry sectors, including energy, automotive, electronics, bioengineering, medicine, aerospace/aeronautics, etc. Laser-matter interaction is a complicated multi-physics process, involving laser absorption, electron excitation, heat/mass transfer, fluid/solid mechanics, and phase/microstructure change. A good understanding of these fundamental mechanisms is crucial for the improvement of precision, efficiency and product quality in these processes. This course will provide students with a fundamental understanding of lasers, optics, laser-matter interaction mechanisms, and various state-of-the-art laser-based manufacturing and materials processing techniques. The techniques to be introduced include micro/nano-scale manufacturing, 3D printing, 3D structuring in bulk materials, organic tissue processing, shock peening, etc. |
