On June 13, 2014, Prof. Ferenc Krausz, director at the Max Planck Institute for Quantum Optics in Garching, chair of experimental physics at the Ludwig Maximilians University in Munich, Germany paid a visit to SIOM and gave high-level seminar at SIOM. Prof. Ruxin Li, Director of SIOM presided over Martin’s seminar. Prof. Krausz expressed his special congratulations on the 50^th anniversary of SIOM during his presentation.

Prof. Ferenc Krausz delivered a presentation entitled by “Some Aspects of Relativistic Optics Using Ultra-Intense Laser Pulses”. He reviewed the symbiosis of electrons and light forms the basis of life: The microscopic motion of electrons creates light which supplies our globe with life-giving energy from the sun. Electrons transform light into biological energy during　photosynthesis and into biological signals endowing us with the capability of seeing the world around us. Upon their　motion inside and between atoms electrons emit light, carry and process information in biological systems and manmade devices, create, destroy, or modify molecules and thereby affect biological function. Consequently, they are　key players in physical, chemical or life sciences as well as information, industrial and medical technologies likewise. Recent advances in laser science have opened the door to watching and controlling these hitherto inaccessible microscopic dynamics, etc.

Ferenc Krausz and his research team were the first to create and measure a light pulse lasting less than one femtosecond. In 2001, Ferenc Krausz and his group were able for the first time not only to generate but also to measure attosecond light pulses by means of intense laser pulses consisting of one to two wave cycles. In 2003 he was appointed director at the Max Planck Institute for Quantum Optics in Garching and in 2004 became chair of experimental physics at the Ludwig Maximilians University in Munich. In 2006 he co-founded the Munich-Centre of Advanced Photonics and began serving as one of its directors. In recent years, Max Planck Institute for Quantum Optics and SIOM have close collaboration and made important developments in the research fields of Laser electron acceleration and Attosecond science.
