Title: Laser-Assisted Advanced Manufacturing: from Fundamental Mechanisms to Engineering Applications

Abstract:

Lasers can be used to deliver energy with extremely wide spectral, spatial, and temporal ranges. These laser properties have provided many opportunities for advanced manufacturing and material engineering. In this presentation, the speaker will give an overview of his research activities in laser-assisted advanced manufacturing and materials processing. Laser-induced shockwave with a high peak pressure can be utilized for surface engineering of structural components towards enhanced materials durability. Laser-induced localized heating can be used for additive manufacturing (3D printing) of metallic materials. Furthermore, laser-matter interactions can be spatially, spectrally, and temporally controlled and optimized for micro-/nano-manufacturing, such as photon-enabled fabrication and processing of nanomaterials. This talk will cover the following research areas: 1) laser shock processing of structural metals; 2) micro/nanostructure integrated metal 3D printing; 3) laser-assisted nanomanufacturing of nanomaterials towards applications in energy storage, biomedical, and soft robotics.
