Researchers at the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) have now successfully combined a table-top laser-based extreme high-order harmonic source for short-pulse soft-X-ray absorption spectroscopy in the water window with novel flatjet technology.  Giacomo Bighin, a postdoc in the group of Mikhail Lemeshko at the Institute of Science and Technology Austria (IST Austria), has now extended the Feynman diagram technique.  When beams of ultra-short laser pulses running in the same direction intersect with each other at a noticeable angle, various interactions occur between the pulses.  In a recent publication in Science, researchers at the University of Paderborn and the Fritz Haber Institute Berlin demonstrated their ability to observe electrons' movements during a chemical reaction.  The special feature of the Kiel system is its extremely high temporal resolution of 13 femtoseconds.  Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology.
