Who stole the light? Self-induced ultrafast demagnetization limits the amount of light diffracted from magnetic samples at soft x-ray energies  
Free electron X-ray lasers deliver intense ultrashort pulses of x-rays, which can be used to image nanometer-scale objects in a single shot. When the x-ray wavelength is tuned to an electronic…  
Self-imaging of a molecule by its own electrons: mapping the atomic motion during a molecular vibration  
One of the long-standing goals of research on the light-induced dynamics of molecules is to observe time-dependent changes in the structure of molecules, which result from the absorption of light, as…  
Strong fields and ultrafast motions – how to generate and steer electrons in liquid water  
Water molecules undergo ultrafast dithering motions at room temperature and generate extremely strong electric fields in their environment. New experiments demonstrate how in presence of such fields…  
Hammer-on technique for atomic vibrations in a crystal  
Vibrations of atoms in a crystal of the semiconductor gallium arsenide (GaAs) are impulsively shifted to a higher frequency by an optically excited electric current. The related change in the spatial…  
Highest peak power and excellent stability - record parameters for amplified ultrashort pulses at 2-µm wavelength and kilohertz repetition rates  
Power-scalable ultrafast laser sources in the midwave-infrared (MWIR) are a key element for basic research and applications in material processing and medicine. Optical amplifiers based on chirped…  
High-order synthetic dimensions in waveguide photonic lattices: parallelizing high-dimensional random walks  
In physics, a very intuitive way of describing the evolution of a system proceeds via the specification of functions of the spatiotemporal coordinates. Yet, there often exist other degrees of freedom…  
Light from inside the tunnel  
Steering and monitoring the light-driven motion of electrons inside matter on the time-scale of a single optical cycle is a key challenge in ultrafast light wave electronics and laser-based material…  
New compressor delivers above-terawatt 1.5-cycle pulses at kilohertz repetition rate  
Researchers at the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) have reached a new milestone in few-cycle pulse generation, breaking a 10-year-old record and achieving…  
Outstanding basic research on light-matter interaction - Max Born Institute successfully evaluated  
In its statement, the Leibniz Association's Senate acknowledges MBI's outstanding research achievements and strong international position. The Senate recommends continuing the joint funding by the…  
Light Moves Spins Around  
Combining experiment and theory, researchers from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) and the Max Planck Institute of Microstructure Physics have…
