Abstract:Manufacturing at microscale, such as CPUs, chips, and microelectronics, has demonstrated its profound impacts and contributed significantly to every aspects of human life. To satisfying the demands on Fast, Better, and Cheaper devices, manufacturing at nanoscale is becoming more and more prominent. Here we are going to introduce related investigations carried out in the Laser Assisted Nano Engineering Lab at the University of Nebraska-Lincoln. By deploying femtosecond lasers as the irradiation source, we successfully achieved (1) direct writing of graphene patterns in open air, (2) additive nanoscale manufacturing using two-photon polymerization (TPP), (3) subtractive nanoscale manufacturing using multiphoton-ablation (MPA), and (4) hybrid nanoscale 3D printing technique.
Keywords:laser, femtosecond laser, graphene, carbon nanotubes, two-photon polymerization (TPP), multiphoton ablation (MPA), nano-fabrication, nano-manufacturing.
Biography:Yunshen Zhou is currently the Assistant Director of Jiangsu Weina Laser Application Technology Research Institute (LATRI). He received his PhD degree in Condensed Matter Physics from the University of Science and Technology of China in 2005. From 2005 to 2016, Dr. Zhou joined Prof. Yongfeng Lu’s research group (Laser Assisted Nano Engineering Lab) at the University of Nebraska-Lincoln as a postdoctoral researcher, research assistant professor, and research associate professor consequently. In 2016, he joined Advanced Optowave (AOC) and INNO Laser and started to work in Changzhou, China. He has published over 70 peer-reviewed journal articles and three patents.His current research focuses on industrial scale laser-enabled applications, laser-based equipment, laser-assisted micro/nano-fabrication& manufacturing, and laser spectroscopic equipment.

Keywords: femtosecond laser, micro-processing, micro-fabrication, industry application.
Cold process, high material removing efficiency and minimum material damages are unique advantages of femtosecond (fs) laser processing due to super-short laser-matter interaction time (10-12- 10-13s) in comparison with nanosecond (ns) lasers. After intensive R&D efforts made in last decades, tremendous progresses were achieved in the performance, reliability and cost of fs lasers, in addition to the established laser-material interactions within the fs regime. Being potent and innovative processing techniques, the fs lasers not only renovate existing production lines but also enable novel applications that were previously extremely challenging or impossible, such as bio-resorbable vascular stent (BVS), engine gasoline direct inject (GDI) nozzles, lithography thin masks, and AMOLED etc.As a laser-processing-solution provider, we are focusing on developing high-performance fs lasers and exploring fs-laser-enabled techniques to serve market quests and achieve the best return of investment (ROI).
In this paper, we will review the state-of-the-art industrial applications of the fs lasers and cover following topics: (i) emerging applications / materials requiring fs lasers; (ii) effect uses of fs lasers; (iii) major challenges of fs lasers and potential solutions. Both experimental results and theoretical models will be demonstrated in fs-laser ablation and material ablation efficiency (MAE).
Dr. Zhang received his Ph.D degree in Laser Chemistry in Institute of Physics, Chinese Academy of Science in 1992.
He has more than 25 years’ experience on laser material processing and device fabrication in both academia and industry, and published more than 50 peer review papers. He has been awarded Alexander von Humboldt (Germany) in 1994 andSTA(Japan) research fellowship in 1996, respectively. In 1997, he won “Prize of Progress” of laser Society of Japan.
Since 2000, he has served as senior scientist in several high-tech companies in Canada and USA, working on laser-based micro-processing/fabrication.
Currently, as principal scientist and director of laser application development, Dr. Zhang is responsible for key laser application development serving Advanced Opto-wave Corporation, USA. Prior to joining Advanced Opto-wave Corporation, he served as senior laser application engineer and technology head in Panasonic Boston Laboratory, USA
