Abstract
Lasers can be used to deliver energy with extremely wide spectral, spatial, and temporal ranges. Laser-matter interactions can be spatially, spectrally, and temporally controlled and optimized to produce and characterize materials with desired efficiency and accuracy. These laser properties have provided many opportunities for material science and engineering which unique applications in manufacturing, energy, and biomedicine. In this presentation, Dr. Yongfeng Lu will introduce his lab’s research activities in processing and characterizing materials in various forms, including metals, polymers, diamond, carbon nanotubes, carbon nanoonions, graphene, gallium nitride, and biomedical materials, with focus on applications in energy and biomedicine. The talk will cover the following research areas:
- Energy coupling using resonant vibrational excitation of molecules (e.g., formation of diamond structures and boron/nitrogen doped diamonds);
- Laser-assisted micro/nanofabrication and additive manufacturing (e.g., target fabrication for laser fusion);
- Laser-assisted optical spectroscopy, imaging, spectrometry, artificial intelligence in spectroscopic imaging (cancer diagnostics, nuclear forensics, and corrosion detection);
- Energy devices and applications (supercapacitors, bolometers, nuclear fusion and fission, algae-based bioenergy);
- Biomedical applications (fat-liver disease, peripheral arterial disease, breast cancers, traumatic brain injury, pancreatic cancers, and cardiac artery disease); and
- Examples of commercialized laser processing technologies.
Biography:
Dr. Yongfeng Lu is currently the Lott Distinguished Professor of Engineering at the University of Nebraska-Lincoln (UNL). He received his bachelor’s degree from Tsinghua University (China) in 1984 and M.Sc. and Ph.D. degrees from Osaka University (Japan) in 1988 and 1991, all in electrical engineering. From 1991 to 2002, he was a faculty in the Department of Electrical and Computer Engineering at National University of Singapore. He joined the Department of Electrical Engineering at UNL in 2002. He has more than 30 years of experience in processing and characterization of micro/nanostructured materials. His group has research projects funded by NSF, AFOSR, ONR, DTRA, DOE, DOT, NCESR, NRI, private companies, and foundations, with research expenditures over $38 million in recent years. His research has led to a number of commercialization and product developments.
Dr. Lu has authored or co-authored 604 journal papers and 524 conference papers (H-index: 75). He served as the President of the Laser Institute of America (LIA) and the President of International Academy of Photonics and Laser Engineering (IAPLE, UK). He has been elected to SPIE fellow, LIA fellow, OSA fellow, and IAPLE fellow. He has also served as chair and general chair for major international conferences in the field including the general congress chair for the International Congress of Applications of Lasers and Electro-Optics in 2007 and 2008, and general co-chair for LASE in Photonics West 2014-2017. He is also the recipient of the prestigious Schawlow Award of LIA in 2016.
