超快激光超精細特種加工

演講課題:超快激光超精細特種加工

演講人:孫洪波

演講摘要:

超快激光微納加工是一種特種超精細加工技術,由于具有極大瞬態功率的超短脈沖光與物質強烈的非線性線性相互作用,使加工技術適用于各種材料,對于透明介質,可以制備三維結構。其“特”就表現在可以加工特種材料、可以實現特殊結構和特定的光、電、機械等性能。本報告介紹報告人的最新實驗進展,以及這一技術走向工業化應用的一些思考。 Laser nanofabrication, particularly that based on femtosecond laser direct writing, has been considered as a powerful tool for machining hard-processing materials from soft to hard, for three-dimensional functional devices. Its power has been manifested by the successful fabrication and demonstration of microdevices in micro-optics, microelectronics, micromechanics, microfluidics, sensing and biomimetics. This talk will introduce the latest progresses along these lines in my lab, particular emphasis will be placed on transparent materials processing for micro-optical devices.

Hong-Bo Sun, received the B.S. and the Ph.D degrees in electronics from Jilin University, Changchun, China, in 1992 and 1996, respectively. He worked as a postdoctoral researcher in Satellite Venture Business Laboratory, the University of Tokushima, Japan, from 1996 to 2000, and then as an assistant professor in Department of Applied Physics, Osaka University, Japan. In 2004, he was promoted as a full professor (Changjiang Scholar) in Jilin University, and since 2017 he has been working in Tsinghua University, China. His research interests have been focused on ultrafast optoelectronics, particularly on laser nanofabrication and ultrafast spectroscopy: Fabrication of various micro-optical, microelectronical, micromechanical, micro-optoelectronic, microfluidic components and their integrated systems at nanoscale, and exploring ultrafast dynamics of photons, electrons, phonons, and surface plasmons in solar cells, organic light-emitting devices and low-dimensional quantum systems at femtosecond timescale. So far, he has published over 400 scientific papers in the above fields, which have been cited for nearly 15000 times, and H factor is 60, according to ISI search report. He is currently the topical editor of Optics Letters (OSA), Light: Science and Applications (Nature Publishing Group), Chinese Science Bulletin (Springer), and editorial advisory board member of Nanoscale (RSC) and Display and Imaging (Old City Publishing). He is IEEE, OSA, SPIE and COS fellow.
