Abstract: Next-generation attosecond metrology (2.0) relies on sub-fs charge carrier injection into wide-gap materials. The injected carriers can be used to directly probe fundamental processes of ultrafast optoelectronics and sample optical fields up to PHz frequencies. Light fields from the infrared to the ultraviolet, with accurately measured temporal evolution, serve as a unique probe for the polarization response of matter. Field-resolved spectroscopy will access valence electronic as well as nuclear motions in all forms of matter and constitutes a generalization of pump-probe approaches. The multi-MHz-rate synthesis and measurement of infrared waveforms with 1-attosecond-scale precision opens the door for real-world applications. They include probing of human health by measuring miniscule changes of the molecular composition of blood (liquid biopsy) via field-resolved vibrational molecular fingerprinting.
Bio: Prof. Ferenc Krausz earned his degree in Electrical Engineering at the Technical University Budapest (1985). He completed his doctorate in laser physics at the Technische Universität (TU) in Vienna (1991) where he continued in the same research field in 1993, took up assistant professorship in 1998 and full professorship in 1999. In 2003, he was appointed Director of the Max-Planck-Institute of Quantum Optics (MPQ) in Garching. In October 2004, he became professor at the Faculty of Physics of Ludwig-Maximilians-Universität (LMU) in Munich and has since then held the Chair of Experimental Physics – Laser Physics. In a series of experiments performed between 2001 and 2004, Ferenc and his team succeeded in producing and measuring attosecond light pulses and applying them for the first real-time observation of atomic-scale electronic motions. These achievements earned him the reputation as the co-founder (along with Paul Corkum) of the field of Attosecond Physics, a scientific discipline devoted to real-time observation and control of electron phenomena, as also acknowledged by their selection as 2015 Thomson Reuters Citation Laureates. More recently, he turned his attention to capitalizing on ultrafast laser techniques for disease detection by the molecular fingerprinting of human bio-fluids.
