报告摘要: Electronic motion is a key process in a wide range of modern technologies, including micro- to nano-electronics, photovoltaics, bioinformatics, molecular biology, and medical as well as information technologies. The atomic-scale motion of electrons typically unfolds within tens to thousands of attoseconds (1 attosecond [as] = 10-18 s). Recent breakthroughs in laser science are now opening the door to watching and controlling these hitherto inaccessible microscopic dynamics [1]-[12].
　  Attosecond technology is based on strong, well-controlled electric fields of few-cycle laser light. These controlled light fields permit control of microscopic electric currents on the atomic scale just as microwave fields permit control of currents on nanometer-scale semiconductor chips. By analogy to microwave electronics, we have dubbed this new technology “lightwave electronics” [10,12]. Lightwave electronics provides – for the first time – real-time access to the motion of electrons on atomic and sub-atomic scales. Insight into and control over microscopic electron motion are likely to be important for developing brilliant sources of X-rays, understanding molecular processes relevant to the curing effects of drugs, the transport of bioinformation, or  the damage and repair mechanisms of DNA, at the most fundamental level, where the borders between physics, chemistry and biology disappear. Lightwave electronics – once implemented in condensed matter – will be instrumental in advancing electronics and electron-based information technologies to their ultimate speed: from microwave towards lightwave frequencies.

报告人简介：Ferenc Krausz was born in Mor, Hungary, on 17 May 1962. He was awarded his M. S. in Electrical Engineering at Budapest University of Technology in 1985, his Ph. D. in Quantum Electronics at Vienna University of Technology in 1991, and his "Habilitation" degree in the same field at the same university in 1993. He joined the Department of Electrical Engineering as Associate Professor in 1998 and became Full Professor in the same department in 1999. In 2003 he was appointed as Director of Max Planck Institute of Quantum Optics in Garching, Germany, and since October 2004 he has also been Professor of Physics and Chair of Experimental Physics at Ludwig Maximilian's University of Munich. His research has included nonlinear light-matter interactions, ultrashort light pulse generation from the infrared to the X-ray spectral range, and studies of ultrafast microscopic processes. By using chirped multilayer mirrors, his group made intense light pulses comprising merely a few wave cycles available for a wide range of applications and utilized them for pushing the frontiers of ultrafast science into the attosecond regime. His most recent research focuses on attosecond physics: the control and real-time observation of the atomic-scale motion of electrons. He co-founded Femtolasers GmbH, a Vienna-based company specializing in cutting-edge femtosecond laser sources.
