Biography:
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, Osaka, Japan. In 2005, he was promoted as a full professor (Changjiang Scholar) in Jilin 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, microoptoelectronic, microfluidic components and their integrated systems at nanoscale, and exploring ultrafast dynamics of photons, electrons, phonons, and sur plasmons in solar cells, organic light-emitting devices and low-dimensional quantum systems at femtosecond timescale. So far, he has published over 200 scientific papers in the above fields, which have been cited nearly 7000 times 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).

报告摘要：
超快激光一般是指脉冲宽度短于10 ps (皮秒：10-12秒) 的脉冲激光，主要指短皮秒和飞秒（10-15秒）激光。这个时间尺度短于激发态电子向晶格弛豫能量的所需时长，使光与物质相互作用呈现了与通常光激发显著不同的特性，也促成了其崭新的光电应用。围绕飞秒激光与物质相互作用快（作用时间短）、强（瞬态功率高）、细（非线性使作用区体积小，用作加工分辨率高）的特点，报告人开展了系列研究，包括飞秒激光超快光谱用于光电电光转换动力学探索，激光诱导气体成丝用于近程遥感探测，以及飞秒激光微纳加工用于新原理、新材料微纳集成器件的制备。本报告将介绍相关研究的进展。

Abstract:
Ultrafast laser is type of pulsed laser with pulsewidth shorter than 10 ps, including mainly sub-10 ps and femtosecond lasers. The principle of light-matter interaction on this case differs significantly from those by long-pulse lasers, bringing about numerous novel applications. In the past years, our research has been focused on the exploration of new features of femtosecond laser interactions with matter, and their applications on optoelectronics, including (i) ultrafast spectroscopic study of optoelectronic and electro-optical conversion dynamics, (ii) femtosecond laser radar for remote sensing based on the laser-induced filamentation in the gas phase, and (iii) laser micronanofabrication for novel functional integrated devices. The talk will summarize our recent research progress.
